Humility is the key to oneness with God. Consequently, it is also the key to oneness with our brethren. God's way of achieving oneness is for each person to be so attuned to God that he is motivated to do everything possible to ensure that the relationship (with God or fellow man) is not only unbroken, but constantly becoming ever closer. We should do this because we are striving to become like Him, and that is how He is.

Each person is responsible for cleaning up his character and humbling himself before God. Each is not responsible for judging his brother so critically it drives a wedge between them and separates them. Such a person does not even see his own sin! In such a case, he could not be in God's Kingdom because that manner of thinking would continue right on into it, and God will not allow it there.
