We do not all believe in the same God. We have different things that we worship. Whatever we worship is our god. So, we do not have the same God. We do not all believe in the same God.
There is the true God. He is the God of the church. He is the God who created the entire universe. He is the one that we should all worship. People run after the wrong god. That is why they worship animals and crafted images.
What should we do? We should show the world the true God. We should lead them to the light. Jesus is the Light of the world. He is the Bread is life. He is the life which the world needs. Those who do not have Jesus Christ have no life.
Why we have the light of God's Word is so that we can lead the lost to Jesus Christ.
