What are New Age religions like according to the Bible?
The Bible characterizes New Age religions as pagan at their core. Though they may speak persuasively, their fundamental conduct is anti-Christian and anti-God, manifesting wickedness. They resemble the Canaanites who deepened in iniquity until God's judgment fell, and the Gentile world approaches that same condition.
Les explains that with the advent of all these New Age religions, they are pagan; they may talk a good line, but their basic behavior is anti-Christian, anti-God, and wickedness in one way or another. He parallels this to the Canaanites, whom God gave 400 years to straighten up their act before their iniquity was full. Instead they went deeper and deeper into wickedness, so God told Joshua and the children of Israel to destroy them and not spare a single one. Les warns that the Gentile world is fast approaching the same place, though God remains patient, gracious, and kind, letting man take his own way for now.
