Psalm 66:18 (KJV)
18 If I regard iniquity in my heart, the Lord will not hear me:
Numbers 20:10 (KJV)
10 And Moses and Aaron gathered the congregation together before the rock, and he said unto them, Hear now, ye rebels; must we fetch you water out of this rock?
2 Corinthians 12:8-10 (KJV)
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.
