In what ways is the God of the Bible different from other gods?

Nothing it’s all made up

There was once a university debate about what made Christianity unique among all the world's religions. Passing by, hearing the debate, C.S. Lewis enquired what it was all about. Upon hearing it was to know what made the Christian God unique, he said, "Oh, that's easy. It's the grace of God."  Anybody who says they have read all about the God of the Bible but who has failed to be in awe of the unmerited grace of God on sinners who are in rebellion against Him has not read with any understanding.

There is only one God and one day your going to meet him in person.

Jehovah is GOD ALMIGHTY, he is not fashioned by man’s hands, He is the living and True God. Jeremiah 10:10-12

He created man, the universe and ALL things. 

A GOD OF PURPOSE

25 Although it may be hard for our minds to understand, Jehovah never had a beginning and will never have an end. He is the “King of eternity.” (Psalm 90:2; 1 Timothy 1:17) Before he began to create, Jehovah was all alone in universal space. Yet he could not have been lonesome, for he is complete in himself and lacks nothing. It was love that moved him to begin to create, to give life to others to enjoy. God’s first creations were spirit persons like himself. He had a great organization of heavenly sons even before the earth was prepared for humans. Jehovah purposed for them to find great delight in life and in the service he gave them to do.—Job 38:4, 7.

26 When the earth was prepared, Jehovah placed a couple, Adam and Eve, in a part of the earth already made into a paradise. It was his purpose that they have children who would obey and worship him, and who would extend that paradise all over the earth. (Genesis 1:27, 28) As we have learned, however, that grand purpose was interfered with. Adam and Eve chose to disobey God, and his purpose has not been fulfilled. But it will be, for it would be admitting defeat for Jehovah not to accomplish what he purposes. And that he could never do! “Everything that is my delight I shall do,” he declares. “I have even spoken it; I shall also bring it in.”—Isaiah 46:10, 11.

27 Do you see where you can fit into God’s purpose? It is not simply by doing whatever you want without considering what God’s will is. That is what Satan and Adam and Eve did. They knew what God’s will was but they did not do it. And God held them accountable. Are we, too, accountable to God? Yes, because God is the Source of our life. Our life is dependent on him. (Psalm 36:9; Matthew 5:45) To what extent, then, do we live our lives in harmony with God’s purpose for us? We should think seriously about this, because our opportunity for everlasting life depends on it.

In that Man is his top priority.  And he exists.

There is little difference.   All gods are delusions clung to because we are afraid to die.  But the body turns to dust or ashes.  So people created the idea of soul -  something that doesn't exist - so we can make sense out of life after death.

The God of the bible is alive and exerts power (Hebrews 4:12) God's word in itself has a strong influence on people who read and apply what it says. The wisdom found in the Bible contains power to change peoples lives for the better. The bibles message can lead honest hearted ones to everlasting life. In Jeremiah 10:3-5 the bible describes worship to false gods with terms such as 'delusion' or 'useless'. God tells his people to stop associating with those who practice false worship or worship other gods ( 2 Corinthians 6:14-17).

The principle way would be the fact that He exists.

The God of the Bible is the God of creation. All others come from that which was created.
