Have you ever wondered exactly what it means to be “born again?” Jesus told Nicodemus in John 3:3, “Unless one is born again, he cannot see the kingdom of God.” What was He talking about?
Well, think about it: What does a baby understand of the world when he is in the womb? Very, very little. There are some sounds and lights that get to the fetus, but does he understand them? No. Not until the baby is born does he start understanding the outside world. Jesus was saying that it’s the same thing in the spirit. When you accept Jesus into your life, you’re being born into a spiritual world. Then you start growing. A baby takes in everything, is curious about everything, and gets input from everyone around him, and slowly but surely grows. He starts learning about simpler things—simple shapes, mother’s milk—and gradually gets into more challenging things, like crawling, talking, reading, and eating solids. It’s the same thing with new Christians. After being “born again,” there is a lot to learn. This is why Peter says, “As newborn babes, desire the pure milk of the word, that you may grow thereby” (1 Peter 2:2).
