When you reach a conclusion about something in your mind, the kind of conclusion that dismisses all contingency and remedy, rendering the whole situation finite, which is what scripture refers to as ‘judging’, you have succeeded in taking away God from that situation, because you have rejected the infinite nature of God.
That is why you must not judge. Allow God alone to be judge and jury in every matter. JUDGE NOTHING, JUDGE NOT YOURSELF AND JUDGE NO ONE. LEAVE ROOM FOR GRACE(DIVINE CREATIVITY).
