Prove from the Bible that eternal life is only granted on certain conditions. Man disobeyed God's law, and was brought under the power of the law of sin and death. Man is now a death-doomed creature in need of redemption. Acknowledgment of the true nature of flesh is the basis of forgiveness of sins. God extends mercy and forgiveness to all who come unto Him through Christ, and acknowledging their fallen state, seek to overcome through the means He has provided.
Baptism is the first act of obedience.
It is only valid after an understanding and acceptance of the first principles of God's purpose. It is absolutely essential to salvation. See Acts Ch. Though the grave may claim us, our resurrection to life eternal is assured if we seek God in the way appointed. We, too, therefore, can likewise triumph over the serpent power through Christ.
