“We worship God authentically when we know him truly and treasure him duly. Then the word “worship” refers to that valuing, that inner valuing, becoming visible in the world in two basic ways in the New Testament.

One is acts of the mouth: acts of praise and repentance in worship services or small group gatherings.

The other is acts of love with the body and the hands and the feet: acts of love that show the supreme value of God by what we are willing to sacrifice for the good of others.” John Piper
