Note 15 at Mt. 5:25: Hard feelings have destroyed many friendships. However, it goes against human nature to humble ourselves and seek reconciliation. But the Lord gives us two important reasons to do so. (1) Hatred in the heart (either ours or theirs) is just like the act of murder and puts a person in danger of hell fire (v. 22), and (2) if we don't choose the way of peace, even if that means personal loss, as in turning the other cheek (v. 39) or going the extra mile (v. 41), then we run the danger of having the judge decide against us and having to suffer the consequences. If we choose the way of strife instead of peace, the Lord will not defend us. We will have to live with the results (v. 26; Lk. 12:58-59).

It's important to realize that not everyone is going to reconcile with you regardless of what you do. This was true of Jesus, Peter, Paul, etc. However, Jesus is stressing the need to do all we can to end the strife. "If it be possible, as much as lieth in you, live peaceably with all men" (Rom. 12:18).

Note 16 at Mt. 5:25: There is a spiritual application of this verse, too. If we repent and put our faith in Jesus, our Savior, it's like settling out of court with God. We don't have to appear before Him at the great white throne judgment (Rev. 20:11-15).
