Don't judge a book by its cover, they say. Are you a mind reader or a discerner of motives? You may not know the contents of a [different] book or some other thing until it is revealed. Maybe you know what is on someone's mind, or maybe you really know or maybe you really really know, or not? Should you jump to conclusion before you know (understand)? This is how relationships -family, friends etc, are divided or destroyed. This is the enemy's plan. 'United we stand, divided we fall.'

"Very few, even very few Christians, have the true gift of discernment. Without this gift it is impossible to accurately discern truth in those of the present or the
past. Even with this gift it is difficult. Until you have been here, and been stripped, you will judge others through distorted prejudices, either positive or negative. That is why we were warned not to judge before the time. Until we have been here we just cannot really know what is in the heart of others, whether they are performing good or evil deeds. There have been good motives in even the worst of men, and evil motives in even the best of them. Only here can men be judged by both their deeds and their motives....

The wise judge themselves lest they be judged. The even wiser ask for the judgements of the Lord, because they realize that they cannot even judge themselves well...." - excerpts from The Final Quest by Rick Joyner.

Romans 14:1-23
King James Version (KJV)
4 Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand....
19 Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
Shalom.
