John 4:22–24
You worship what you do not know; we worship what we do know, for salvation is from the Jews. / But a time is coming and has now come when the true worshipers will worship the Father in spirit and in truth, for the Father is seeking such as these to worship Him. / God is Spirit, and His worshipers must worship Him in spirit and in truth.”
1 Corinthians 14:15
What then shall I do? I will pray with my spirit, but I will also pray with my mind. I will sing with my spirit, but I will also sing with my mind.
