Unless one is born again, he cannot see the kingdom of God. John 3:3
Jesus spoke these words to Nicodemus, a religious man, but was spiritually bankrupt.
What does that mean?
It means to be “born from above, born of the Spirit.” It is a radical heart change that only God can do. You might think, “Well, I’m not one of those ‘born again’ type.” According to Jesus, you can’t be a genuine Christian without being born again. That can be brought about only by the work of the Holy Spirit. If this was true for Nicodemus, a great teacher of Israel, it is certainly true for all of us. We must be born again. All we have to do is simply accept the work of Jesus’ death on the cross and allow the Holy Spirit to work in us. It is a marvelous miracle of mercy.
