If you are singing the songs as a member of the assembly of the saints, then don't just sing, but think. What are you singing? How does it point you to Jesus as He reveals Himself in His Word? What truths are being laid on your heart, and how is your singing being used to lay them on the hearts of those around you? Which lines in the lyrics flood you with joy because they move you to consider Christ afresh...

The biggest difference between the Psalms and much of our modern music today is not (as many think) the length of songs, or the lack of repetition, or of the lesser use of the "I" pronoun - it is the breadth and depth of the character of God and how we as His creation humbly find our place within that.

When... you stand to sing, consciously focus on what is going on... Ask God to help you focus; think about the words you are singing and the images they are painting; respond in prayer to lines that particularly strike you; be mindful of those around you, enjoying being part of something greater than just yourself.
