“The LORD made a covenant with them and commanded them, ‘You shall not fear other gods or bow yourselves to them or serve them or sacrifice to them, but you shall fear the LORD, who brought you out of the land of Egypt with great power and with an outstretched arm. You shall bow yourselves to him, and to him you shall sacrifice. And the statutes and the rules and the law and the commandment that he wrote for you, you shall always be careful to do. You shall not fear other gods, and you shall not forget the covenant that I have made with you. You shall not fear other gods, but you shall fear the LORD your God, and he will deliver you out of the hand of all your enemies.’ However, they would not listen, but they did according to their former manner. So these nations feared the LORD and also served their carved images. Their children did likewise, and their children’s children—as their fathers did, so they do to this day.”
Those who espouse that there are many ways to God (even if they believe and teach that Christianity is the most accurate and highest revelation of God known to humanity) are espousing syncretism. They teach that we can worship Jehovah and still have other belief systems and views about God, and that this is acceptable to God as long as we are sincere because our revelation of God is not yet complete.
The above passage from 2 Kings 17:35-41 shows that God is against this mixture of religious belief (ecumenism, pluralism or syncretism) and only tolerates worship of the one true God.
