In John 3:5-8 Jesus is talking to a religious leader, Nicodemus. Nicodemus comes to Jesus in the night because he longs to hear what Jesus has to say. His heart wants to know more because inwardly Nicodemus knows to whom he is talking to.
Jesus tells him that he must be born again of water and spirit. He tells Nicodemus that, “That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.” This idea puzzles Nicodemus since all he knows and lives by is the flesh. Jesus on the other hand is trying to tell Nicodemus that the world of the spirit is different than the world of the flesh. Jesus tells him that the spirit is eternal while the flesh is not. Jesus also wants Nicodemus to see that he cannot enter the kingdom of Heaven without being born of water and spirit.
Our lives here on earth are temporary at best. One person once said to me that our life is like the speck of dust on the head of a pin. The pin sits on the earth and that represents eternity, the dust speck represents our lives spent here on earth. The question each of us has to ask of ourselves, “Where do we want to spend eternity?” Nicodemus was given the opportunity to turn from his present life, accept Christ as his savior and receive the Holy Spirit.
We don’t know what happened to Nicodemus, but God does. Those of us that are seeing fewer years ahead of us than behind us see how finite life can be. Especially those of us that have lost many loved ones. Christ accepted the thief on the cross during this man’s last moments of life. Can we afford to wait? Knowing Christ brings life, "Real Life to us, not just living and existing. All one has to do is to ask Jesus to come into our life today. We don't know if we will have a "tomorrow." When we allow someone into our home, we open the door from the inside first. Ask Jesus into your life today.
