Justification can be explained as a process of being acquitted from sin by God. It is a process by which man's sin is forgiven and over-looked by God as a saving grace for eternal life. The conditions for the achievement of justification can be stated as follows: Justification is a gift of God's grace. It cannot be attained by man's effort or his perfection. It was the wish of Jesus to carry man's sin on the cross, therefore, man has the choice of rejecting it, but the consequence of rejection is destruction.
A Christian, therefore, has to believe in the resurrection of Jesus as a first step to justification. It is the confession of a man's faith with his mouth that can earn him salvation. Those who are trusting in the righteousness of the law (Jews and Gentiles) have fallen short of the Grace of God. Those who would be accepted by Jesus when he comes back are those who accept him in faith.
