And this is life eternal, that they might know thee the only true God, and Jesus Christ whom thou has sent. There should be a love for other Christians. There should be a change in what the person likes to do. My sheep hear my voice, and I know them, and they follow me. For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto the end.
True faith is a belief that causes on to act on what is believed.
Those who believe in the biblical sense of the term will follow their Lord. The true child of God may grow weak, he may stumble, but he will not quit. Those who finally and completely turn their backs on Our Lord and Saviour were never truly of us. They may have know the truth, given assent to the truth, tasted the good things of God, and even felt the working of the Holy Spirit in their lives, but they have never truly received the free gift of salvation that is in Jesus Christ. The believer does not keep himself.
