Anything can become an idol. If you worship even your own endeavors for Christ, these are nothing more than the work of your own hands. It is possible to have a wrong understanding of God, also. Anyone that does not believe God is a God of love, but also a God of wrath, judgement, righteousness, and law, has created a god to suit themselves. This also is idolatry. My advice. Don't put your trust in the theology as of late, and forget about another's concept of the Lord, and just read Scripture alongside heartfelt prayer. I fear the modern church has a mistaken view of what God is like, and therefore the church is not as it should be. We are no different than rebellious Israel. Look at the men of history that saw revival and you will find that something was different then (they relied on the Holy Ghost).Psalm 24:3-5 "Who shall ascend into the hill of the LORD? or who shall stand in his holy place? He that hath clean hands, and a pure heart; who hath not lifted up his soul unto vanity, nor sworn deceitfully. He shall receive the blessing from the LORD, and righteousness from the God of his salvation."
