James 5:15-16

And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven.
Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much.

John 3:1-7

There was a man of the Pharisees named Nicodemus, a ruler of the Jews.
This man came to Jesus by night and said to Him, “Rabbi, we know that You are a teacher come from God; for no one can do these signs that You do unless God is with him.”
Jesus answered and said to him, “Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.”
Nicodemus said to Him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”
Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
Do not marvel that I said to you, ‘You must be born again.’”

John 15:5-10

I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.
If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned.
If you abide in Me, and My words abide in you, you will ask what you desire, and it shall be done for you.
By this My Father is glorified, that you bear much fruit; so you will be My disciples.
As the Father loved Me, I also have loved you; abide in My love.
If you keep My commandments, you will abide in My love, just as I have kept My Father’s commandments and abide in His love.

Romans 6:1-4

What shall we say then? Shall we continue in sin that grace may abound?
Certainly not! How shall we who died to sin live any longer in it?
Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death?
Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

Galatians 3:10-14

For as many as are of the works of the law are under the curse; for it is written, “Cursed is everyone who does not continue in all things which are written in the book of the law, to do them.”
But that no one is justified by the law in the sight of God is evident, for “the just shall live by faith.”
Yet the law is not of faith, but “the man who does them shall live by them.”
Christ has redeemed us from the curse of the law, having become a curse for us (for it is written, “Cursed is everyone who hangs on a tree”),
that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith.
