John 3:3 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.
What specifically is it about the Kingdom of God that we cannot see until we become born again.
Romans 14:17 For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.
When we become born again God enlightens us about righteousness. He gives us a far superior understanding of what is right and what is wrong. Furthermore, there is peace and joy for the citizens of the kingdom of God that they could not perceive or enjoy before they become part of that kingdom.
Luke 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
We cannot look upon the hearts of men and know that they have become born again. But we can be pretty confident that men have been born again by the changes in their lives and the fruit they bear. They will begin doing the will of God and continue doing His will more and more.
Matthew 7:20 Wherefore by their fruits ye shall know them. 21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Spiritually blind unbelievers are all around us. Pray for them and whenever the Lord leads, share the gospel with them so they might be saved. This is not blindness of the eyes beside their noses, it is the blindness of their hearts.
John 12:40 He hath blinded their eyes, and hardened their heart; that they should not see with their eyes, nor understand with their heart, and be converted, and I should heal them.
