“Truly, truly, I say to you, he who does not enter by the door into the fold of the sheep, but climbs up some other way, he is a thief and a robber. But he who enters by the door is a shepherd of the sheep. To him the doorkeeper opens, and the sheep hear his voice, and he calls his own sheep by name and leads them out. When he brings all his own out, he goes ahead of them, and the sheep follow him because they know his voice. A stranger they will never follow, but will flee from him, because they do not know the voice of strangers.” This figure of speech Jesus spoke to them, but they did not understand what those things were which He had been saying to them.
So Jesus said to them again, “Truly, truly, I say to you, I am the door of the sheep. All who came before Me are thieves and robbers, but the sheep did not hear them. I am the door; if anyone enters through Me, he will be saved, and will go in and out and find pasture. The thief comes only to steal and kill and destroy; I came that they may have life, and have it abundantly.
“I am the good shepherd; the good shepherd lays down His life for the sheep. He who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees—and the wolf snatches and scatters them— because he is a hired hand and is not concerned about the sheep. I am the good shepherd, and I know My own and My own know Me, even as the Father knows Me and I know the Father; and I lay down My life for the sheep. And I have other sheep, which are not from this fold; I must bring them also, and they will hear My voice; and they will become one flock with one shepherd. For this reason the Father loves Me, because I lay down My life so that I may take it again. No one takes it away from Me, but from Myself, I lay it down. I have authority to lay it down, and I have authority to take it up again. This commandment I received from My Father.”
A division occurred again among the Jews because of these words. And many of them were saying, “He has a demon and is insane. Why do you listen to Him?” Others were saying, “These are not the words of someone demon-possessed. Can a demon open the eyes of the blind?”
At that time the Feast of the Dedication took place at Jerusalem; it was winter, and Jesus was walking in the temple in the Portico of Solomon. The Jews then gathered around Him, and were saying to Him, “How long will You keep us in suspense? If You are the Christ, tell us openly.” Jesus answered them, “I told you, and you do not believe; the works that I do in My Father’s name, these bear witness of Me. But you do not believe because you are not of My sheep. My sheep hear My voice, and I know them, and they follow Me; and I give eternal life to them, and they will never perish—ever; and no one will snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of the Father’s hand. I and the Father are one.”
The Jews picked up stones again to stone Him. Jesus answered them, “I showed you many good works from the Father; for which of them are you stoning Me?” The Jews answered Him, “For a good work we do not stone You, but for blasphemy; and because You, being a man, make Yourself God.” Jesus answered them, “Has it not been written in your Law, ‘I said, you are gods’? If he called them gods, to whom the word of God came (and the Scripture cannot be broken), do you say of Him, whom the Father sanctified and sent into the world, ‘You are blaspheming,’ because I said, ‘I am the Son of God’? If I do not do the works of My Father, do not believe Me; but if I do them, though you do not believe Me, believe the works, so that you may know and continue knowing that the Father is in Me, and I in the Father.” Therefore they were seeking again to seize Him, and He eluded their grasp.
And He went away again beyond the Jordan to the place where John was first baptizing, and He was staying there. And many came to Him and were saying, “While John did no sign, yet everything John said about this man was true.” And many believed in Him there.
— John 10:1-42

As He passed by, He saw a man blind from birth. And His disciples asked Him, saying, “Rabbi, who sinned, this man or his parents, that he would be born blind?” Jesus answered, “Neither this man nor his parents sinned, but this was so that the works of God might be manifested in him. We must work the works of Him who sent Me as long as it is day; night is coming when no one can work. While I am in the world, I am the light of the world.” When He had said this, He spat on the ground, made clay of the saliva, and rubbed the clay on his eyes, and said to him, “Go, wash in the pool of Siloam” (which is translated, Sent). So he went away and washed, and came back seeing. Therefore the neighbors, and those who previously saw him as a beggar, were saying, “Is not this the one who used to sit and beg?” Others were saying, “This is he,” still others were saying, “No, but he is like him.” He kept saying, “I am the one.” So they were saying to him, “How then were your eyes opened?” He answered, “The man who is called Jesus made clay, and rubbed my eyes, and said to me, ‘Go to Siloam and wash’; so when I went away and washed, I received sight.” And they said to him, “Where is He?” He said, “I do not know.”
They brought to the Pharisees the man who was formerly blind. Now it was a Sabbath on the day when Jesus made the clay and opened his eyes. So the Pharisees also were asking him again how he received his sight. And he said to them, “He applied clay to my eyes, and I washed, and I see.” So then some of the Pharisees were saying, “This man is not from God, because He does not keep the Sabbath.” But others were saying, “How can a sinful man do such signs?” And there was a division among them. Therefore, they said to the blind man again, “What do you say about Him, since He opened your eyes?” And he said, “He is a prophet.”
Then, the Jews did not believe it of him that he was blind and had received sight, until they called the parents of the very one who had received his sight, and questioned them, saying, “Is this your son, who you say was born blind? Then how does he now see?” So his parents answered and said, “We know that this is our son, and that he was born blind; but how he now sees, we do not know; or who opened his eyes, we do not know. Ask him; he is of age, he will speak for himself.” His parents said this because they were afraid of the Jews; for the Jews had already agreed that if anyone confessed Him to be Christ, he was to be put out of the synagogue. For this reason his parents said, “He is of age; ask him.”
Therefore, a second time they called the man who had been blind, and said to him, “Give glory to God; we know that this man is a sinner.” He then answered, “Whether He is a sinner, I do not know; one thing I do know, that though I was blind, now I see.” So they said to him, “What did He do to you? How did He open your eyes?” He answered them, “I told you already and you did not listen. Why do you want to listen again? Do you want to become His disciples too?” And they reviled him and said, “You are His disciple, but we are disciples of Moses. We know that God has spoken to Moses, but as for this man, we do not know where He is from.” The man answered and said to them, “Well, here is a marvelous thing, that you do not know where He is from, and He opened my eyes. We know that God does not listen to sinners; but if anyone is God-fearing and does His will, He listens to him. Since the beginning of time it has never been heard that anyone opened the eyes of a person born blind. If this man were not from God, He could do nothing.” They answered and said to him, “You were born entirely in sins, and are you teaching us?” So they put him out.
Jesus heard that they had put him out, and after finding him, He said, “Do you believe in the Son of Man?” He answered and said, “Who is He, Lord, that I may believe in Him?” Jesus said to him, “You have both seen Him, and He is the one who is talking with you.” And he said, “Lord, I believe.” And he worshiped Him. And Jesus said, “For judgment I came into this world, so that those who do not see may see, and that those who see may become blind.” Some of the Pharisees who were with Him heard these things and said to Him, “Are we blind too?” Jesus said to them, “If you were blind, you would have no sin; but now that you say, ‘We see,’ your sin remains.
— John 9:1-41

Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, through whom also we have obtained our introduction by faith into this grace in which we stand; and we boast in hope of the glory of God. And not only this, but we also boast in our afflictions, knowing that affliction brings about perseverance; and perseverance, proven character; and proven character, hope; and hope does not put to shame, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us.
For while we were still weak, at the right time Christ died for the ungodly. For one will hardly die for a righteous man, though perhaps for the good man someone would dare even to die. But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from the wrath of God through Him. For if while we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life. And not only this, but we also boast in God through our Lord Jesus Christ, through whom we have now received the reconciliation.
— Romans 5:1-11

For by grace you have been saved through faith, and this not of yourselves, it is the gift of God; not of works, so that no one may boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them.
— Ephesians 2:8-10

God is for you, who can be against you?

What then shall we say to these things? If God is for us, who is against us? He who indeed did not spare His own Son, but delivered Him over for us all, how will He not also with Him graciously give us all things? Who will bring a charge against God’s elect? God is the one who justifies; who is the one who condemns? Christ Jesus is He who died, yes, rather who was raised, who is at the right hand of God, who also intercedes for us. Who will separate us from the love of Christ? Will affliction, or turmoil, or persecution, or famine, or nakedness, or peril, or sword? Just as it is written,
“For Your sake we are being put to death all day long;
We were counted as sheep for the slaughter.”
But in all these things we overwhelmingly conquer through Him who loved us. For I am convinced that neither death, nor life, nor angels, nor rulers, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the love of God, which is in Christ Jesus our Lord.
— Romans 8:31-39

How blessed is the man who does not walk in the counsel of the wicked,
Nor stand in the way of sinners,
Nor sit in the seat of scoffers!
But his delight is in the law of Yahweh,
And in His law he meditates day and night.
And he will be like a tree firmly planted by streams of water,
Which yields its fruit in its season
And its leaf does not wither;
And in whatever he does, he prospers.

The wicked are not so,
But they are like chaff which the wind drives away.
Therefore the wicked will not rise in the judgment,
Nor sinners in the congregation of the righteous.
For Yahweh knows the way of the righteous,
But the way of the wicked will perish.
— Psalm 1:1-6
