The true light that gives light to every man was coming into the world.
John 1:9
Man, the carnal man, lives in darkness. All mankind has turned aside from the truth, the true light, and has gone to corruption. There is nothing wholesome about man, and nothing good in what he can do. Ever.
The Spiritual Man, however, as Paul described, has died to it. He has died to himself, to the world with all its desires, and has died to himself. The case is so edged that Paul states that he is crucified to the world and the world is crucified to himself (Galatians 6:14).
You are the light of the world. A city set on a hill cannot be hidden;
Matthew 5:14
Salvation is a supernatural event. God’s Spirit comes in and regenerates the dead human spirit, making a person alive again. When a human believes, a change takes place, that changes a human being, dead in their trespasses and sins as they were, to being a new creation in Christ (2 Corinthians 5:17).
A man does not need to be told or convinced that he has been born again, or saved, by any other person. Affirmation and good Bible study is always advisable, and continued pointing to the truth of the Word of God is always recommended, but, when a man is changed, he knows it on the inside.
He who thinks he knows something does not yet know as he ought.
1 Corinthians 8:2 (paraphrase)
The most interesting thing about the gospel is that, you could have all the words right, you could say all the right things, have all the right demeanor and mannerism, you could know when to shout and how to dance, but you could be just as much of a devil as Judas was. That’s right. It’s what’s on the inside that counts.
You don’t have what it takes. You never have, and you never will. If you can do it, it isn’t God, and it needs to die.
