Not saying that this is the only possible approach, but I find that all ills and philosophies and intellectual masks come down to a misunderstanding or rejection of these foundational Scriptural truths:
1. Holy God
2. Sinful man
3. Grace through Christ
Each apprehended in proper sequence resolves nearly every other question; it also puts one in the proper relationship to God for the Holy Spirit to work.
Your right on brother- thats what it comes down to-
