We can become Christians by believing in Jesus Christ as our Savior from sin. This is called the new birth, and it is the most important decision we will ever make in our lives.
The first step: Understanding the need for a savior (the corrupted nature).
The scripture instructs that as by one man’s disobedience, many were made sinners, so also by one Man’s obedience, many will be made righteous. (Romans 5:18) NKJV. It means you are a sinner today, not simply because of the sin you did this morning – you are a sinner because you inherited the sinful nature from Adam – the first man, and the reason why you sin is that you are a sinner. Therefore, sinful nature needs to be changed into the nature of righteousness first and foremost; after that, one can start living out the righteous nature.
The Second Step: How to become a Christian (correcting nature from sinful to righteous nature)
The Scripture instructs that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness, and with the mouth, confession is made unto salvation. (Romans 10:9-10) NKJV.
So if you believe the above statements in steps one and two then you can pray as follows: Jesus today I give my heart to you, I believe you came to die on the cross and were resurrected from the dead to pay for my sin, cleansed me from all sin, and gave me eternal life.
Today I surrender my life to you Jesus, and I ask that you come into my heart and be my Lord and personal savior. Amen.
The next thing to do is to find a good bible teaching Christian Church - like ICGC Life Temple to join so you can learn more about the Christian faith, have fellowship with other believers, and learn the tenets of the Christian faith to enable you to live a righteous life.
However, do not forget to study the bible yourself as well. Your salvation must be so valuable to you as to let anyone distract or misdirect you. We also have available great written content to read for growth in the faith.
