Idol worship is not an Old Testament only thing as the verses below show. In fact, 1 John 5:21 is addressed to New Testament believers and admonishes us to "Keep yourselves from idols. Amen."
1Co 12:2 "Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led."
2Co 6:16 "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."
1Th 1:9 "For they themselves shew of us what manner of entering in we had unto you, and how ye turned to God from idols to serve the living and true God;"
1Jo 5:21 "Little children, keep yourselves from idols. Amen."
Re 2:14 "But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication."
Re 2:20 "Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols."
Re 9:20 "And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:"
In Acts 12:20-23 gives the account of Herod giving a great oration and the people shouted, "It is the voice of a god, and not of a man." Verse 23 tells us that "immediately the angel of the lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost."
In Acts 14:11-15 the people wanted to worship Paul and Barnabas,
"And they called Barnabas, Jupiter; and Paul, Mercurius, because he was the chief speaker." Acts 14:13 "Then the priest of Jupiter, which was before their city, brought oxen and garlands unto the gates, and would have done sacrifice with the people." This greatly troubled Paul and Barnabas and they rent their clothes and ran in and cried in verse 15, "Sirs, why do ye these things: We also are men of like passions with you, and preach unto you that ye should turn from these vanities unto the living God..." Then in verse 18 they still wanted to do sacrifice to them.
"Idolatry" is used only five times in the Bible and four of those are in the New Testament.
It is sad that in our day, most of the idol worship is of mankind. Yes, there are those who worship at images, but that is not my thought at this time. I am speaking of the development of idol worship in our present day that has reached an all-time high. There are those who give more honor and respect to man than God. No doubt Bear Bryant was a unique man, maybe even a good man. I doubt he wanted the kind of man-worship he has received living and dead, but the fact is, there are people who speak greater swelling words of him than the God that blessed and created him. There have been people in the sports world and the entertainment industry that have garnered more worshippers to themselves than God. Just as sad is the fact that many Christians give more time, money and attention to the earthly "stars" of our day than to the Lord Jesus Himself. There are at least a dozen references to God being "a Jealous God." Most of those cases are regarding His jealousy over His people and their idolatry.
My dear friends, there is not a man on the earth that is worthy of worship, and we should never make an idol in our lives out of anyone or anything. Consider this: Anything or anyone we put before God or in the place of God becomes an idol. A person; a hobby or habit; a goal in life; a worldly star such as singer or musician; sports "star"; actor or actress; even any personal property. These things should never become the compelling and controlling thing in our lives instead of the Lord. How do you know if you have an idol? Whatever you give your time, talent, affection, worship to instead of the Lord has become an idol. If you are a Christian and you stayed out of Church last Sunday night to
watch the "Super Bowl", you put an idol in God's place. 1Co 10:14 "Wherefore, my dearly beloved, flee from idolatry."
