The highest form of worship goes on in heaven as we speak, where “the living creatures give glory and honor and thanks to Him who sits on the throne” (Revelation 4:9).  At the lowest end of the gratitude continuum is the reprobate mind where “even though they knew God, they did not honor Him as God or give thanks” (Romans 1:21).  Paul teaches that it is reprobation not to glorify, honor and thank God.  Gratitude is to join heaven’s worship to glorify, honor and thank Him.  Gratitude syncs us with heaven’s worship.
