Idolatry is simply put, the worship and adoration of any representation that is on earth or in the heavens. Any one who puts anyone or anything before God is an idolater; idolatry is an abomination before God. God is a jealous God and desires that only He is to be worshipped. John 4:24 is about seeking those who will worship Him in Spirit and in truth. Idolators cannot worship the Lord in Spirit and in Truth because they worship images. Their gods are false.
The Bible writes of gods who can neither speak nor hear. Their eyes are not opened because they cannot see. They cannot answer prayer, nor are they creators of life. They are created by man. Paul writes in Romans 1 of idolators and those of the world who were neither thankful. They did not glorify God nor worship Him in spirit and in truth for they were unrepentant in their deeds. They were sinful and godless. Idolators are foolish in that they worship impersonal gods some of which are either embodiments of people or are themselves humans. Human beings cannot forgive sin for we are fallible. We can be used as instruments of God, but that does not mean we are gods, nor should we as humans expect others to worship any of us.
Idolators are foolish in that they are missing out in the blessings that worshipping the True God brings. They don't realize how good they would have it worshipping the Lord because they are outside the kingdom of God. They are deceived into thinking someone or something else is worthy of greater adoration than He. Idols or other gods do not love us. They will not show us mercy nor can they save or deliver. They are cold and lifeless. They are devoid of love and compassion. They should be forsaken and not appeased. They cannot bring everlasting joy and peace. They certainly cannot bring everlasting life. Only our Heavenly Father can do that for He alone can answer prayer. He is the Only God that is worthy of fear and reverence. He is omnipotent and omniscient; He knows all and sees all.
None of the other gods or idols are eternal, for they are corruptible and bring about corruption. The end for idolators is destruction. Unrepentant idolators, those who go "whoring after other gods" will have their part in the Lake of Fire. They are amongst those outside of the gates of the city for they are unbelievers for they have not been forgiven, born-again Christians, or followers of Christ. They have degraded themselves for false gods in exchange for appeasement against disaster, sickness, and death. Those who believe in and follow the Lord Jesus do not degrade themselves. They love, serve, and honor only the Lord. Jesus Christ is their only Lord and only He can save.
Repent of idolatry, for Jesus is the Only Way, Truth, and Life and no man can come to the Father except Him. He is the Vine and the Husbandman. He is faithful and True. Who or what is your God? Buddha? Allah? Money? Sex? Don't let it stand in the way of having a relationship with Jesus Christ. Turn to Him, for He alone can save and deliver. No other god can do that.
