Acts 2 [.mp3]

2 And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.

Acts 15 [.mp3]

8 And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
9 And put no difference between us and them, purifying their hearts by faith.
