"We Walk by faith and not by sight" 2 Cor.5:7
One of the most frustrating and self-defeating forms of behavior is to live in your head. Typically used as a coping mechanism, but for a Christian, we are to live in the world, and not cope but conquer! Jesus did tell us that he has overcome the world.
Our faith is to contend with whatever obstacles stand in our way. Living in our head is not real, and is not a system of thinking designed to accomplish and achieve our purpose, but just to cope with the reality of life. So get out of your end and walk by faith and trust obstacles in the way of you accomplishing your purpose will be moved!
