Progressives love to portray the Christian religion (and all religion, for that matter) as fundamentally a matter of being on a spiritual “journey”. Religion is primarily about “exploring” for ourselves what we think about spiritual matters.
The problem is that hidden within this approach is an enormous (and unspoken) assumption, namely that God has not clearly revealed himself. Nor has he clearly revealed a message about salvation. Indeed, the assumption underlying this entire progressive narrative is that religion is about humans finding God, rather than about a God who has revealed himself to humans.
If someone thinks such a thing, you could see why he or she would be irritated with biblical Christianity. According to progressives, religion (by definition!) is always in flux. It’s a process of seeking God. How arrogant would it be to claim he’s been found. In contrast, biblical Christianity argues that God has clearly revealed a message of salvation in Christ Jesus, and that all people everywhere are called to believe in that good news.
Even more fundamentally, the progressive position misses the core Christian message. Christianity is not about mankind’s never-ending “journey” to God, but about God’s completed journey to us, to save us from our sins. As John reminds us, ” In this is love, not that we have loved God, but that he loved us and sent his Son to be the propitiation for our sins” (I John 4:10).
