We walk by faith because He has asked us to. In fact, He has said there is no other way to know Him.
Soldier of The Cross, if you do not know, do not guess. And avoid those who do the guessing. God is clear and right.
Know the Word of God. Know the written Word for yourself.
If you have to know why, where, when or how, you are not proceeding by faith.
Take His outstretched hand.
Look up and move on.
