When the Apostle Paul arrived in Athens in the seventeenth chapter of the book of Acts, his spirit was in heaviness as he saw all the false idols; and as he continued through the city he saw an alter to the "unknown god".
Christians are usually the first to condemn idol worshippers (and we should, condemn the practice, not the sinner; pray for the sinner that God would give them the heart for repentance), but do not hold themselves to the same standards as they hold the "heathen". What do I mean? Just this, many Christians are guilty of worshipping "an unknown god". Many create a god in their mind that they are comfortable with and then worship that god. The problem is that many times that is not the God of the Bible and so they are guilty of worshipping "an unknown god", certainly unknown to the pages of Scripture.
So many times many Christians are not comfortable with the God that the Scriptiures represents. For example;
They do not want a God who is almighty. Oh, they do for selfish reason. They want the almighty God to get them out of a jam. But so many times they do not want an almighty God that makes claims on their lives, that requires things of them, that demands worship, that demands faithfulness, that demands a singularity of devotion. Because so many do not want the authority that the almighty God requires. They want, as Jane Russell used to say, "My sweet Daddy in the sky". That kind of view of God is blasphemy and an unknown god".
People are comfortable with a god that meets their needs, gives them their greeds and makes no demands on their lives. Now, I will tell you that if you have been convinced that that is the proper view of God, then you have been watching too much TBN. Their channel line-up is filled with people who will tell you that the god of the Bible wants you healthy and wealthy. That, as Joel Osteen put it, make your order for God to fill. Listen, this is paganism and not the God of the Scriptures.
The God of the Scriptures is absolutely Sovereign, absolutely holy, absolutely almighty, absolute in power, absolute in knowledge, absolute in grace, absolute in justice, absolute in omnscience, absolute in righteousness, absolute in authority, absolute in rule, absolute in lordship, absolute in creative design.
The God of the Bible is not the unknown god that many people try to worship. He is Lord, He is sovereign; worship Him, not the god of our minds.
