The number one thing to do is ADMIT you are a sinner and worthy of spending eternity in Hell. If you can do that then you are halfway “Born Again.”
The second thing to do is to PERSONALLY ACCEPT Jesus Christ as your Lord and Savior.
John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
The third and final step is to simply BELIEVE AND HAVE FAITH that God the Father has forgiven you, and that you have been adopted into the Holy Family.
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
Hebrews 11:2 For by it the elders obtained a good report.
That’s it, you are done!
You are now a new creature, no need for any outward show, the change is a spiritual one, not a physical one!
Now if you have never read the Bible, that is fine, but it would be wise to start reading and obeying the truth as it is revealed to you in the Bible. As a Christian start with the New Testament, and do not try to read the Bible as if it were some magical book with hidden meanings. Just read it as a child would, simply believing everything you read.
It is the simplest book to understand, and do not be like the Jewish people who say the average person cannot understand it and has to study the Talmud. For they are blind and cannot see the simplicity of the Word of God, for the main reason is that THEY DO NOT BELIEVE in Jesus the Christ (Messiah).
All can be saved with the Gospel. Hitler did not have to go to Hell if he followed the 3 simple steps above.
If you're stuck and not sure what to do, simply allow the Holy Spirit to guide you to the truth! Do not resist him!
Sin is sin, and it only takes 1 sin to seal your doom in the Lake of fire. All are forgivable, but not all accept the FREE gift of God. Please do not harden your heart. Get saved right now, this moment, for tomorrow is not guaranteed.
