Praise the Lord
Looking up the definition of the word "praise", I read that it means "to set a price on", or "to commend the worth of, to express approval or admiration of, to laud the glory of, to extol". And it is offered in response to what another has done ... in response to their deeds.
I don't normally think about praising Jesus/God and when I hear the phrase "Praise the Lord", my mind adds the next line, "... and pass the ammunition" :-) (link) But sometimes I am grateful for the things I think he's done for me, for his deeds, and then sometimes I sing to him.
The one thing I miss the most about going to church is the music, and if , as Psalm #150 says, music qualifies as praise, then I did participate in it. Now that I'm not at church, I still sing to Jesus/God ... I sing the songs from a few "religious" music CDs (Taize and Robin Mark) but I think what he most likes are the songs of Peter and Gordon ... :-)
Nobody I know could love me more than you
You can give me so much love it seems untrue
Listen to the bird who sings it to the tree
And then when you've heard him, see if you agree
Nobody I know could love you more than me
