For us to get to Heaven, we must believe in the Gospel. To be born again, we must know and believe that Jesus Christ has saved us from all our sins by taking them on Himself and by shedding His blood on the Cross and dying for us.
We need to realize that it is not through our prayers of repentance or some effort of our part that we are born again. Our own efforts have nothing to do with the washing away of sin.
Because the Lord took upon Himself all our sins and paid the wages for them, which is death by being crucified, shedding His blood, dying on the Cross, rising from the dead, and then returning to the Father's right hand in Heaven that we receive the free gift of eternal life.
