Psalm 103:1 (KJV)
"Bless the Lord, O my soul; and all that is within me, bless his holy name."
(a) all of his benefits
(b) forgiving all your iniquities, and
(c) healing all your diseases
When I consider the inclusiveness of such a wide scope of God's mercies and concerns I conclude David has something very right.
He goes on to say God redeems our lives from destruction and He crowns us with loving kindness and tender mercies. If David is addressing memory and recall in the soul realm, then he furthers his argument by saying there is something sitting on your head; "loving kindness and tender mercies". These are the dominant thoughts of someone who has allowed God to make inroads into his thought life through praise. He continues by saying the impact of a mind that is settled on God's truth, according to verse 5, is a mouth filled with good things. The result is that our youth is restored like the Eagles.
A good word to use here is transforming your mind. When you view yourself, it is not how forgetful you are or how old you look or how many wrinkles you have. The dominate thoughts are you are surrounded by God's kindness and mercy. What a way to live. It is a magnificent idea living your life everyday in a healthy manner that is God honoring. There is a New Testament verse that parallels this teaching. It is found in Romans 12:2. That verse says, "Don't be conformed to this world, but be transformed by the renewing of your mind." The word transformation in the Greek carries the meaning to metamorphosis.
You are morphing into something beautiful because of the impact and the effect of the word of God upon your mind.
David concludes by saying, "bless the Lord all His works (which is you and I) and all places of His dominion (our minds)". He finalizes the psalm by saying, bless the Lord O my soul which reaffirms his first statement. I think this psalm gives a very clear case for our minds to be stayed on God through praise, reiteration and continuance, being mindful of all that God has done and is doing through the power of His word in you.
