There are no more important words written than those of John 3:1-20. Exactly what does it mean to be "born again?"
To be "born again" means to believe in Christ Jesus. It mans to grasp His Gospel (I Corinthians 15: 1-6) with both hands, and heart and mind, and trust him with our whole heart, mind, soul and strength. Because, the only unforgivable sin on this earth or in heaven is unbelief.
My dear old mother taught us a simple prayer of belief: "Now I lay me down to sleep, I pray my Lord my soul you keep, if I should die before I awake, I pray you Lord my soul you take."
This simple, faithful prayer is a beautiful thing, because without faith it is impossible to please God, "for he/she that comes to God must believe that He is and that He is a rewarder of them that diligently seek Him" (Hebrews 11:6).
Being "born again" is something we must do. We must simply believe. Child-like trust is a beautiful thing (Matthew 18:1-7).
