These are Jesus' guidelines for dealing with those who sin against us. Jesus' words are not a license for a frontal attack on every person who hurts or slights us. They are designed to reconcile those who disagree so that all Christians can live in harmony.
By contrast, we should go to the person first, as difficult as that may be. Then we should forgive that person as often as he or she needs it.
Ideally, the church's decisions should be God-guided & based on discernment of his Word. Handling problems God's way will have an impact now & for eternity.
Jesus looks ahead to a new day when he will be present with his followers not in body, but through his Holy Spirit. Two or more believers, filled with the Holy Ghost, will pray according to God's will, not their own; & thus their requests will be granted.
