God created us in His image. We are made in pthe likeness of God. We possess the virtues and qualities that make us resemble God.
When we are talking about the image of God, what is it that comes to our heart? Do we think that our physical body looks like that of God's? No! God is not a human like us. He does not have one head with two eyes like us. He is not tall or short like some of us. The likeness of God is not our physical appearance. We should not forget that God is a spirit.
The Bible says that God is a spirit. That is why it tells us that those who must worship God must do so in spirit and truth. We are not connecting to God physically. We only relate with God through spiritual means. God cannot be seen with physical eyes.
In the likeness of God means that we have the attributes which God is identified with. God is holy. So, holiness is the likeness of God that is in us. Anyone who is not holy does not resemble God. The Bible admonishes us to be holy because our God is holy.
We also know that our God is love. Those who do not have love are not born of God. If someone is not born of God, then such might be born of the devil. So, the question which we must answer is whether we are of God or of the world.
