Acts 15:7-9

And when there had been much questioning, Peter rose up, and said unto them, Brethren, ye know that a good while ago God made choice among you, that by my mouth the Gentiles should hear the word of the gospel, and believe. And God, who knoweth the heart, bare them witness, giving them the Holy Spirit, even as he did unto us; and he made no distinction between us and them, cleansing their hearts by faith.
