23But the hour is coming, and is now here, when the true worshipers will worship the Father in spirit and truth, for the Father is seeking such people to worship him. 24God is spirit, and those who worship him must worship in spirit and truth.
JOHN 4:23-24 (ESV)

EPHESIANS 5:19 (ESV)
1I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. 2Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
ROMANS 12:1-2 (ESV)
