I have to disagree strenously with this point. NEVER stop using the noggin. "Love the Lord... with all your MIND". Clear thinking isn't everything, of course, but without it, chaos results.
God and the Holy Spirit are not perceived with the noggin...He cannot be grasped intellectually. He can only be grasped spiritually (which includes the body, soul, mind...and then some). God uses the human mind to an incredible degree. But the key is the spirit. His Spirit speaks to our spirit.
If what I am saying is chaos...ask Him in prayer. You will see, He is not chaos.
God bless.
Thanks to all for the thoughtful posts; this is exactly what I was hoping for. There are so many philosophical questions here, not the least of which is, "do I blindly accept the bible as it's written, or do I use the faculties that God has given me to ask and to search"? If God didn't want me to think and to question, why make it possible for me to do so?
