Psalm 103:1 says, “Bless the Lord, O my soul; and all that is within me, bless His holy name!” The Hebrew word for bless means to praise. David was commanding his entire being to align in praise. 

Our soul speaks of our mind, will, and emotions. I like to think of it as a braid. Three strands: our mind leads off and our will and emotions follow. A braid intertwines. Hebrews 4:12 says that His word pierces, “…even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart.”

The Lord knows our heart. Matthew 15:8 says, “These people draw near to Me with their mouth, and honor Me with their lips, but their heart is far from Me.” David knew this. Jesus quoted it from Isaiah 29:13.

Matt Redman wrote The Heart Of Worship. He brought his congregation back into focusing only on the Lord. In part: You’re looking into my heart. I’m comin’ back to the heart of worship, and it’s all about You. It’s all about You, Jesus.
