1 Corinthians 14:25 in the King James Version
And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.
Context
24 But if all prophesy, and someone unbelieving or unlearned comes in, he is reproved by all, and he is judged by all.
25 And thus the secrets of his heart are revealed. So he will fall down on his face and worship God, declaring that God is among you indeed.
26 What is it then, brothers? When you come together, each one of you has a psalm, has a teaching, has a revelation, has another language, or has an interpretation. Let all things be done to build each other up.
