Rob Bell clearly is not a Christian and is working with Satan's Liberals to destroy the Word of God.
The truth will set you free. Bell is not free and indeed is under the influence of sin and that is where his philosophies come from. Like all reprobates, the unsaved part of mankind he cannot perceive truth and the Laws and doctrines of Scripture. As 2Thessalonians states; - "10 And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. 11 And for this cause God shall send them strong delusion, that they should believe a lie: 12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness."
So Bell like the other Liberal reprobates is deluded and cannot receive the love of God's truth. The alternative is that Bell loves Satan's vile lie and is blinded by him.
God states that homosexual practice is an abomination which "defiles" the person and the very land we live in. The hebrew for "defile" is, - "to be foul, especially in a ceremonial or moral sense (contaminated)" - So Bell wants people, church and nation to be foul and contaminated. Clearly Bell works and thinks in direct opposition to God and His creation.
