Why Not Worship Jesus Plus Other gods?

In order to be saved, you must believe in Christ ALONE as your Savior. He is the only way, not one of the ways.

There are many false gods, but only one living God.

jesus is the only way to heaven

Man-made Idol is not God:

God indeed hates idol worship. God created the earth and all the creations in it. Man was created in God's image and was given authority over all other creatures. It is foolish for man to forget the creator and worship the creation of his own hand. Those man-made idols have ears but they cannot hear. They have eyes but cannot see. Be wise. Worship the Creator, Not the Creations.

Isaiah 37:19
And have cast their gods into the fire: for they were no gods, but the work of men's hands, wood and stone: therefore, they have destroyed them.
Isaiah 42:8
I am the Lord: that is my name: and my glory will I not give to another, neither my praise to graven images.

Devil is not God:

Satan and his demons have some power, but their power is limited and not equivalent or greater than God's power. The devil can perform signs, wonders and miracles too. Even today, many people are deceived by seeing the miracles of the devil, the power of witchcraft, fortune-tellers etc.
They do not realize that the living God's power is extremely greater that all the evil powers. The devil can only do what God allows Him to do.

Deuteronomy 32:17
They sacrificed unto devils, not to God; to gods whom they knew not, to new gods that came newly up, whom your fathers feared not.

God hates idol worship:

Worshiping another god, is totally intolerable and unacceptable to God. An idol can be a molten image, a stuatue, money, fame, power, beauty or even your loved ones. Anything that takes or replaces God's place in your life is your god.

Exodus 20:3
Thou shalt have no other gods before me.
Worshiping other gods can never profit you anything, but only make God's wrath remain against you.

Who is Satan?

Why didn't God just cancel out Sin instead of punishing His Son?
