Isaiah 43:1-2

But now, thus says the LORD, who created you, O Jacob,
And He who formed you, O Israel:
“Fear not, for I have redeemed you;
I have called you by your name;
You are Mine.
When you pass through the waters, I will be with you;
And through the rivers, they shall not overflow you.
When you walk through the fire, you shall not be burned,
Nor shall the flame scorch you.”

Ephesians 6:13-17

Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.
Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness,
and having shod your feet with the preparation of the gospel of peace;
above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one.
And take the helmet of salvation, and the sword of the Spirit, which is the word of God.

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.’”
