One must not think that their rebirth from sin depends on their own good deeds. 

To save us from the sins of the world and to make us God's children in the likeness of His image, Jesus, who is the true God Himself, received and accepted the sins of the world. 

To bear the condemnation of sin, He was crucified and shed His blood on the Cross and rose from the dead. He has enabled us to be born again as God's children.

We humans can be transformed into the people who belong in Heaven according to God's plan, but only if we are born again by believing the Gospel.
