As I have noted before, I don't believe that the religion of modern America is Christianity, but rather Deism, i. e., the belief that there is a God, but He doesn't take an active role in the world. Americans love our religiosity, as long as it doesn't interfere with our own sovereignty over our lives! Just enough religion to be comfortable, but not enough actually to affect how we live.
The problem is this: the God of the Bible doesn't allow Himself to be boxed in that way. He has a discomfiting habit of insisting that He is God and we aren't.
Consider Psalm 115:3, "Our God is in the heavens; he does all that He pleases." Short but straightforward. As is Psalm 103:19, "The LORD has established his throne in heaven, and his kingdom rules over all." And again in Psalm 135:6, "The LORD does whatever pleases Him, in the heavens and on the earth, in the seas and all their depths." The sovereignty of God was a favorite theme of the psalmists.
the Prophet Isaiah chimes in on the theme. Isaiah 14:24 and 27, "The Lord of hosts has sworn: 'As I have planned, so shall it be, and as I have purposed, so shall it stand... For the Lord of hosts has purposed, and who will annul it? His hand is stretched out, and who will turn it back?'" For, as the prophet also says in Isaiah 42:8, "I am the LORD; that is my name; My glory I give to no other, nor my praise to carved idols."
And the Prophet Amos gives us God's words in Amos 3:6, "Is a trumpet blown in a city, and the people are not afraid? Does disaster come to a city, unless the LORD has done it?" He declares that God is even sovereign in bringing disaster. Job reinforces this point in Job 2:10. "'Shall we receive good from God, and shall we not receive evil?' In all this Job did not sin with his lips." The inspired text even reinforces his point by telling us that Job's comment wasn't sinful!
American evangelicalism is sinfully man-centered, especially that portion known as the "Prosperity Gospel." In contrast, the Bible is radically God-centered. I suspect that this is the reason that the bulk of American evangelicalism is losing membership and growing increasingly impotent. God has given the professing Christians what they wanted: their own spiritual sovereignty. And it has destroyed our nation's spiritual heritage.
