Question: Evangelist James Robison has openly declared [that] God is using Glenn Beck. How many have addressed the issues that Beck has addressed this past three years? Yes, he's mixed up on theology, but so was Balaam's ass! Matthew:3:9 states that if God's children do not do their part in assuming their responsibilities, "God will raise up children through these stones." John the Baptist got executed for doing that. Paul got thrown into prison for shutting down an idol-manufacturing business in Ephesus. If evangelical pastors want to straighten out Beck, they should adopt his courage in their own ministries, with the addition of correct Biblical theology.
Response: God may be using Glenn Beck, but if that's the case then it is certainly not as an oracle of truth. He may seem to be a champion of conservative politics, for which we would laud him were it not for the fact that he has mixed his erroneous theological beliefs with his misunderstanding of American history. For example, he declared at last year's Liberty University commencement ceremony that it was "God's finger that wrote the Declaration of Independence and the Constitution. This is God's country. These are God's rights." Try to find the "pursuit of happiness" as an unalienable right in Scripture. You should also be aware that Latter-Day Saints' prophets declared that the U.S. Constitution would come under attack and be severely weakened, yet it will be restored by true followers of the Mormon faith.
You wrongly imply that the biblical examples you cite are acts of social and political activism. Not even close--although you are reflecting ideas that are greatly influencing evangelicals today. Pastors who love Jesus yet have addressed the political issues that Beck has "addressed in the past three years" have very likely been diverted from the exhortation that Jesus gave Peter to feed His sheep the Word of God.
The main problem as we see it is not "straighten[ing] out Beck with correct biblical theology,"although we do pray for his salvation. Our primary concern is regarding those who profess to follow Christ yet are abandoning "correct biblical theology," which is the only basis for a fruitful life in Christ--temporally and eternally.
