“Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.” (John 3:3).
Notice that in our opening verse the Lord Jesus didn’t say, "Except a man be born again, he cannot enter the Kingdom of God." He said, "he cannot see." He’s saying, in other words, that the Kingdom of God is here present. You can’t see it until you’re born again and have the life of that Kingdom. The Kingdom of God is the totality of God’s influence that covers the world and Heaven. It’s everywhere, but its manifestation isn’t everywhere.
God sent Jesus to establish the Kingdom of Heaven. The Kingdom of Heaven is that part of the Kingdom of God that is headed by Jesus Christ and established in the Earth through the Gospel. You become a part of that Kingdom when you receive Jesus as your Lord, when you are born again. When you’re born again, you start 'seeing' differently. You see what others don’t see, you hear what others don’t hear, you know what others don’t know. And yet you may be physically in the same earthly location as they.
Remember, when God spoke to Jesus, the people said it thundered. Some said, "An angel spoke to Him." They didn’t understand, and yet we were given the meaning of the words.
So, really, "Except a man be born again, he cannot see the kingdom of God" means: he can’t hear or know it. But when you’re born again, you have insight into divine mysteries and secrets. When you read the Bible, you can understand it, because the Spirit of God in you unveils the Word to you. He makes the mysteries of the Kingdom clear to you, for it is written, "…it is given unto you to know the mysteries of the kingdom of heaven…" (Matthew 13:11).
Dear Father, I thank you for bringing me into the Kingdom of your dear Son, according to your own mercy, by the washing of regeneration and renewing of the Holy Spirit. I’m grateful for your Kingdom, which is in my heart, and for the Holy Spirit in me Who unveils the mysteries of the Kingdom to me with the ability to appropriate spiritual realities, in Jesus’ Name. Amen.
