2 Timothy 2:22-24

Run away from youthful lusts—pursue righteousness, faith, love, and peace with those [believers] who call on the Lord out of a pure heart. But have nothing to do with foolish and ignorant speculations [useless disputes over unedifying, stupid controversies], since you know that they produce strife and give birth to quarrels. The servant of the Lord must not participate in quarrels, but must be kind to everyone [even-tempered, preserving peace, and he must be], skilled in teaching, patient and tolerant when wronged.
