2 Tim. 2:24-26 (ESV)
And the Lord's servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil,  correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth,  and they may escape from the snare of the devil, after being captured by him to do his will.
Quite frankly, I think this is my worst weakness, being quarrelsome. Not that I don’t want to be kind to everyone, but it is like I am hardwired for debate. Quite honestly, I like it I think too much. But it is not always helpful. I don’t always correct gently. The goal should always be repentance, leading to a knowledge of truth. That is normally my goal. But I don’t always proceed in a tact that would bring one there. Perhaps growth and maturity will help a bit there.
Though, I do think this has more to do with those inside a congregation already, than those outside. I say this because Paul is giving Timothy pastoral advice. Pastors can learn from this. Sometimes we all like to debate too much, and when we are debating with people who ought to know better, other pastors, it can be frustrating. We need to check that frustration when dealing with those in your congregation who may just have honest questions.
