The difference

"Then you shall again discern between the righteous and the wicked, between one who serves God and one who does not serve Him." Malachi 3.18

Those who are born of the Spirit are essentially different.

If a person says he or she is a child of God but their behaviour is not different from those who live according to the course of this world, they are deceiving themselves.

Those who are born of the Spirit bear the image of God Almighty, that is, His character.

The only way the world will see and know the invisible God is through His children.

As Jesus said, "Who sees Me sees the Father."

My Son

"Then a voice came from heaven, “You are My beloved Son, in whom I am well pleased."

Mark 1:11

The Holy Trinity was identified through the baptism of the Lord Jesus. In that moment, the Holy Spirit came in the form of a dove, and landed on His head. The same happens today with those who are born of God. They're involved by the Spirit of God and then made into Children of God.
