Matthew 1:23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
The difference between the God of the Bible and other gods is that the God of the Bible is with us because He wants to be with us. In the Old Testament He wanted the Israelites to build a Tabernacle in their midst so He could be with them, not just to be out there somewhere but to be with His people. Jesus said that God loved the world and wanted them to know that He was present with them. That is also what this verse in Matthew tells us and why Joseph was told that Jesus would be named Emmanuel, God with us.
Of course God the Creator is everywhere else also, but He wants to be with people whom He made in His likeness, people who can think and love and make things; moral beings.. Solomon said that His delight is with the sons of men. In theology this characteristic of God is called transcendence, meaning that He is above and beyond everything that He has created and none of it limits Him in any way. The word used in theology for God’s interest in and presence with people and His place in history is immanence, somewhat like the word Emmanuel. We might say that God is a real person who is both there and here without any limitation. In fact He can be in Heaven and live in all our hearts. He cares.
A Jewish writer in contrasting the God of the Bible with the god of Islam points out that they worship a being who is not personal but entirely transcendent, that is he is not here at all. That is a world of difference meaning that they have no hope, no joy, no song, no saviour. But we do believe in the God of the Bible who sent His Son Jesus to be with us. To be our joy, our hope, our Redeemer, our song.
Oh that men would praise the Lord for His goodness and His lovingkindness to the children of men. Be thankful unto Him and trust Him. Jesus has come to be with us as Friend, Brother, and Sin Bearer.
