Psalms 103:1-5 (KJV)

1 A Psalm of David. Bless the LORD, O my soul: and all that is within me, bless his holy name.

2 Bless the LORD, O my soul, and forget not all his benefits:

3 Who forgiveth all thine iniquities; who healeth all thy diseases;

4 Who redeemeth thy life from destruction; who crowneth thee with lovingkindness and tender mercies;

5 Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle’s.

How great are the benefits He gives to those who fear Him.
How wonderful is our LORD!
Let us fear Him, love Him, please Him, obey Him and walk in His ways.
