We're told repeatedly in the New Testament that our calling in Jesus is a call to return evil with good, to refuse to retaliate for any wrong done to us, and thus to follow in Jesus' steps.
I have found this helpful for my own life. Who doesn't become angry over an injustice or sin done to them, particularly from those who should know better, that is from other Christians.
We don't want to be walking around with any martyr complex, but life does dish out some nasty little offerings sometimes, which do hurt. A typical worldly way of handling it is just to brush it off in a tough manner. Where is that way found in Scripture? The psalms are full of complaints to God over human enemies in view of the fact that these problems are not right. And God is the God of making things right in the bringing in of his salvation. This is evident in places in the psalms (one prime example).
And Jesus challenges his enemies, yet he goes on, embracing God's will for him in loving his enemies, and in his unique death, dying for them so that they might be saved. And we're to take the same path- so that sinners can be brought to the Savior and other Christians can be drawn closer to God and all of us to each other, in Jesus- yes, right in the face of the trouble.
And we must remember that God will make things right as we trust in him. He will vindicate us as his children, and he will vindicate himself and the truth as found in Jesus, in our lives, as we trust in him to do so.
This is an important aspect of the gospel we're called to proclaim, that we're to live out in this world. By God's grace in Jesus, we can do this. And grow in it, and thus be a blessing of God to others.
