'Bless the LORD, O my soul, and forget not all his benefits' (Psalm 103:2)
There are so many benefits we have from the hand of the Lord - so it is fitting and right that we praise Him. As the Psalm continues:
Psalm 103:2-6 Praise the Lord, O my soul, and forget not all his benefits—  who forgives all your sins and heals all your diseases,  who redeems your life from the pit and crowns you with love and compassion,  who satisfies your desires with good things so that your youth is renewed like the eagle's.  The Lord works righteousness and justice for all the oppressed.
God has provided a way for our sins to be removed from us, through the cross of Jesus - so that our sins are removed from us, as far as the east is from the west.
How often do we fully realise the immense blessings we receive? This is a great incentive to worship!
