James 5:14-16

14Is any one of you sick? He should call the elders of the church to pray over him and anoint him with oil in the name of the Lord. 15And the prayer offered in faith will make the sick person well; the Lord will raise him up. If he has sinned, he will be forgiven. 16Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man is powerful and effective.

2 Corinthians 12:9,10

9But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me. 10That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.

Psalm 103:1-5

1 Praise the LORD, O my soul; all my inmost being, praise his holy name. 2 Praise the LORD, O my soul, and forget not all his benefits- 3 who forgives all your sins and heals all your diseases, 4 who redeems your life from the pit and crowns you with love and compassion, 5 who satisfies your desires with good things so that your youth is renewed like the eagle's.
