God warned us in His Word that we should not worship idols. Idolatry is a sin which God hates. God told his people not to have any other god besides Him. People who worship idols cannot please God. So God does not listen to idol worshippers.
2 Corinthians 6:14-17 (KJV) Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
And what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people.
Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you,
If you want God to listen to you when you call Him or when you pray, you must run away from worship of idols. We cannot serve two masters. We cannot worship idols together with God. Let us worship God with all our hearts and our minds.
Idols are not gods. They are the works of man's hand. They are the imagination of man's heart. When we make gods for ourselves we are dishonouring God.
The Bible says that light and darkness cannot live together. Light and darkness cannot dwell together. Righteousness and unrighteousness cannot work together. So, God does not work with idols. Those who worship idols are not accepted by God.
