Divisions occur not just between disciples and non-disciples but among disciples themselves; over pride, power, loyalties, theology, doctrine, practice, possessions, commitment, unforgiveness, and more. The apostle Paul said these divisions should not be, but he also said that he was not surprised by them. He said, “No doubt there have to be differences among you to show which of you have God’s approval.”
And of course, there will be differences of opinion over that statement and who it is that has God’s approval, but one thing all disciples should agree on is this; even while we “love one another” and “make every effort to keep the unity of the Spirit through the bonds of peace”, ultimately, it is God’s approval that we seek, even the Lord Jesus, who is the Head of the Church and the Master of every disciple. It is to Him that we will have to give an account.
