In the history of the world, no one has been saved by the power of answering and altar call, or by the power of raising a hand, or by the power of saying “the sinner’s prayer,” or by the power of “inviting Jesus into your heart.” That is not what saves you. It is the power of the gospel that God uses to redeem your soul. It is by faith that the power is wrought in you.
