One of my favorite passages from Scriptures is
Matthew 18, verses 15-17:
"If your brother sins, go and tell him his fault between you and him alone. If he listens to you, you have won over your brother. If he does not listen, take one or two others along with you, so that 'every fact may be established on the testimony of two or three witnesses'. If he refuses to listen to them, tell the church. If he refuses to listen even to the church, then treat him as you would a Gentile or a tax collector."
This passage is striking because it makes me an active part of Christ's work of salvation - I can be one who helps someone recognize a fault and turn toward the good.
It can also be terribly intimidating. It turns out that Jesus expects me to be my brother's keeper! If someone is going down the wrong path I can see it, I have a responsibility to help them see that, to share God's mercy and to remind them of their status as heirs to the treasures of heaven.
It's all too easy to dismiss the struggles Ansons of those around us as 'their problem' or at least 'someone else's problem'. The greater gift is to lovingly approach, to point out the sin and to show the better way - just as Jesus does for us.
