Praise is commanded. Confess the Lord with the harp. Sing praises with the psaltery and ten stringed instruments. If you don't feel like praising, then PLAY until you do. Stir your heart to praise the Lord.
Praise is personal.
A new song is your up to date testimony. This is why the enemy makes it difficult for us to praise the Lord. It is the fruit of our lips, but it must come from the heart. The heart that is in tune with the Lord will praise Him. Do it skillfully with a loud noise.
