 speaks, my friend, not just to be heard or perceived. He speaks to be obeyed. That's what it means when he says, he who has ears to hear, let him hear. It's implicit that if you really hear, you'll follow. How do you do that? You take the step. You say that you believe these things in your heart, and with the mouth, confession is made into salvation. You call upon his name. You ask him to forgive you and to come into your life.
