Believing' is more than just accepting that Jesus died for your sin. To confess is to admit that we are responsible for our own sins. That literally means to turn. We must determine not to continue to sin, but to turn and walk away from it.
Faith requires commitment.
He died for all, that those who live should no longer live for themselves but for Him who died for them and was raised again. If you know that Jesus is knocking on the door of your heart, ask Him in. Your friends and family will see this change. He requires honesty and integrity in the workplace. And, your money belongs to God.
