The term "Born Again Christian" has become a pejorative in our modern world. This is partially because we have combined being born again with right wing politics, but also because some are offended with personalizing a relationship with God.
In 1 Peter 1:3 we read: "Blessed be the God and Father of our Lord Jesus Christ, who according to His abundant mercy has begotten us again to a living hope through the resurrection of Jesus Christ from the dead, (I Peter 1:3 NKJV)
If the words: "Born Again" only appeared in the Gospel of John, there might be good argument that we make too much of the idea of spiritual rebirth; but here we see it again. Peter describes being born again in the context of God's sovereign election along with the resurrection of Jesus Christ. To be begotten again is God's choice and it is made possible by the death and resurrection of Jesus Christ.
The Christian is born again into a living hope. This hope of forgiveness of sin and eternity with God in heaven is birthed in us as we are made alive spiritually and remains with us until we are revealed as sons. Our hope is not make believe, it is not disappointing, it is not decaying or dying; it is living. It is always presently with us until time itself is swallowed up by eternity. You were born into this life with the clock ticking until your death. When you are born again, it is unto life that does not end.
