​Romans 6:16-18
16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
17 But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.
18 Being then made free from sin, ye became the servants of righteousness.

​Therefore, to keep me from being too elated, a thorn was given me in the flesh, a messenger of Satan to torment me, to keep me from being too elated. Three times I appealed to the Lord about this, that it would leave me, but he said to me, “My grace is sufficient for you, for power is made perfect in weakness.” So, I will boast all the more gladly of my weaknesses, so that the power of Christ may dwell in me.
(2 Corinthians 12:7-9)

​2 Corinthians 12:8-10
8 For this thing I besought the Lord thrice, that it might depart from me.
9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
10 Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.

​2 Chronicles 7:13-15
13 If I shut up heaven that there be no rain, or if I command the locusts to devour the land, or if I send pestilence among my people;
14 If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land.
15 Now mine eyes shall be open, and mine ears attent unto the prayer that is made in this place.
