“Marvel not that I said unto thee, Ye must be born again.”
That verse is when Nicodemus had come to Jesus and said “Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.”
Jesus went on to say that you MUST be born again to enter into Heaven. What does it mean to BE born again?
To be born again means to have your sins forgiven- and you can only have your sins forgiven if you believe on the Lord Jesus Christ.
You see, we are all sinners. We are born with a sin nature which makes us give in the devil’s many temptations. Our earthly bodies are no good.
That is why Christ dies for us. He died on the Cross, sprinkled His perfect Blood on the Mercy Seat in Heaven and then rose again so you could have the forgiveness for your sins. As soon as you believe in the Lord Jesus Christ and what He has done for you, all your sins, past, present and future, are forgiven- washed away- never to be remembered again. You have become born again.
