Psalm 103 is a very familiar Psalm to most people. Look at verses 1-2:
1 Bless (affectionately, gratefully praise) the Lord, O my soul; and all that is [deepest] within me, bless His holy name! 2 Bless (affectionately, gratefully praise) the Lord, O my soul, and forget not [one of] all His benefits—
We KNOW that we are to "bless the LORD" (Jehovah - the God of the Covenant). The Amplified Bible (above) gives a great definition for "bless"! We are to "affectionately and gratefully praise the LORD"! How do we actually DO this? It is NOT by saying "bless You Lord"! It IS by declaring WHO He IS and WHAT He's DONE! AMEN! The rest of Psalm 103 does a fine job of this! Let's look at verses 3-19:
3 Who forgives [every one of] all your iniquities, Who heals [each one of] all your diseases, 4 Who redeems your life from the pit and corruption, Who beautifies, dignifies, and crowns you with loving-kindness and tender mercy; 5 Who satisfies your mouth [your necessity and desire at your personal age and situation] with good so that your youth, renewed, is like the eagle’s [strong, overcoming, soaring]! 6 The Lord executes righteousness and justice [not for me only, but] for all who are oppressed. 7 He made known His ways [of righteousness and justice] to Moses, His acts to the children of Israel. 8 The Lord is merciful and gracious, slow to anger and plenteous in mercy and loving-kindness. 9 He will not always chide or be contending, neither will He keep His anger forever or hold a grudge. 10 He has not dealt with us after our sins nor rewarded us according to our iniquities. 11 For as the heavens are high above the earth, so great are His mercy and loving-kindness toward those who reverently and worshipfully fear Him. 12 As far as the east is from the west, so far has He removed our transgressions from us. 13 As a father loves and pities his children, so the Lord loves and pities those who fear Him [with reverence, worship, and awe]. 14 For He knows our frame, He [earnestly] remembers and imprints [on His heart] that we are dust. 15 As for man, his days are as grass; as a flower of the field, so he flourishes. 16 For the wind passes over it and it is gone, and its place shall know it no more. 17 But the mercy and loving-kindness of the Lord are from everlasting to everlasting upon those who reverently and worshipfully fear Him, and His righteousness is to children’s children— 18 To such as keep His covenant [hearing, receiving, loving, and obeying it] and to those who [earnestly] remember His commandments to do them [imprinting them on their hearts]. 19 The Lord has established His throne in the heavens, and His kingdom rules over all.
Declare these TRUTHS about the LORD and then add to these all of the wonderful ways that HE has blessed YOU! AMEN! The rest of Psalm 103 is another exhortation for others to bless Him! Here, to help you in this, is Hillsong with "Made Me Glad":
