John 3:3-7 says:
Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?” Jesus answered,“Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.Do not marvel that I said to you, ‘You must be born again.’
This passage above is Jesus’ response to the Pharisee Nicodemus. In John 3:1-2 we see Nicodemus coming to see Jesus, not in the middle of the day, but during the night. Why? Nicodemus was afraid, scared, and ashamed. Afraid because he didn’t want to be aligned or associated with the very Person the entire collection of Pharisee’s hated. Scared because he saw something clearly saw something in Jesus that was different, that was truthful, and wanted to find out what that was. If his friends found out he was going to meet with this outlaw named Jesus, his reputation would be done. I think too, along with being afraid and scared, that he was ashamed. Because he recognized “different-ness” in Jesus, he wanted to see Him, but didn’t want to come in broad daylight. Part of Nicodemus had to think that Jesus would be aware of his reasons for coming at night rather than in the day, but Jesus being full of grace and truth responds and cuts straight to the heart, revealing the main issue for every human being, ever.
You must be born again. You must be born again. “Born again” connotates such a disgraceful, anti-intelligent, antiquated belief to most people today. Yet for Jesus, it is pressing. So pressing in fact, to embrace it means life and to ignore it means death. Unless you’re born again what? You see 3:3? If you’re not born again you cannot SEE the kingdom of God. You go about doing life on this planet being blind to the most foundational and real truths in existence. Blindness is the non-Christians main problem, and this blind is due to sin (see 2 Cor. 4:4-6 and Eph. 2:1-10). After Nicodemus misunderstands Jesus, Jesus makes it clearer for him. Not born again as an infant by flesh, but born again as in born into the Kingdom of God by the Spirit. Nicodemus seemed to understand this, and merely responded with a question in John 3:9, “How can these things be?” The answer, found in John 3:10-21, is profound and is the home of the most famous passage of the whole Bible, John 3:16.
You have a problem, your sin has blinded you. To correct this, you must be born again. Then you will SEE the kingdom of God, and what people see they usually embrace wholeheartedly.
