What is born of the flesh is flesh, and what is born of the Spirit is spirit.
[John 3:6 NET]
Like produces like. To be born of the Spirit–is to have a new life imparted by the Spirit. This new life will be like that which produces it. Everyone who is born of God–will have some features of God’s likeness. He will love the things that God loves, and hate the things that God hates. In some measure, he will be like God . . .
If we would know what God is like–we have only to look at Jesus Christ, for He was the image of God; and if we are born again, we shall have the same features in our lives! They will be dim at first; but they will come out clearer and clearer each day, as we grow in grace.
We can tell whether or not we are born again–by looking closely at ourselves to see if we have the marks of the Spirit in our life. Do we hate sin? Do we love holiness? Do we love the Bible and prayer, and fellowship with the Lord’s true people?
We have the same thought presented by Paul under the figure of the seal of the Holy Spirit. All Christians are sealed by the Spirit. The seal impresses its own features on the wax. So the Holy Spirit seals believers–by stamping His own image on their hearts. Those who have received the Spirit–will bear the marks of His beauty in their lives!
