Colossians 3:16 (RSV)
From Christian Vegetarian Association (CVA)

Let the word of Christ dwell in you richly, teach and admonish one another in all wisdom, and sing psalms and hymns and spiritual songs with thankfulness in your hearts to God.

When Jesus' teachings of compassion, mercy and peace dwell in our hearts, we are able to witness God's love for us and Creation. Spreading compassion, love and peace is certainly a way to praise God.
 
When Jesus' teachings of compassion, mercy and peace dwell in our hearts, we are able to help our brothers and sisters in Christ to be more obedient to God. With thankfulness in our hearts we need to praise our Creator.
