The Confused Confusion that is prevalent in Christendom today is a result of wrongly dividing the word of truth.
The question that needs to be asked is who is to give us understanding regarding rightly dividing the word of truth...the scriptures?
If we take to heart what Timothy says in his second epistle and consider what he says in ch, 2, verse 7, ...the Lord give thee understanding in all things." we at least know who we should receive our understanding from! The sad part about it is that much of Christendom does not consider what he says therefore are self-deceived into believing that the understanding that men feeds them is the right understanding.
This is often accepted because the expounders are accepted as the spiritual pipeline that flows spiritual understanding from God to man. This bypasses the instruction from God that His Holy Spirit is to be the revealer of spiritual matters.
Now, God does use man to instruct us but, we have to be constantly aware that man teachers are prone to allowing their environment, their belief system to influence their understanding and pass that on as being God ordained in their teaching of it.
