That's an excellent suggestion. We don't know how the Lord will use our prayers...we can only respond to His prompting to pray as he directs.
It's never easy to pray for people that you feel have wronged you. That's when we have to commit our efforts to the Lord. This is an issue over which I am still struggling. I understand that justice is the Lord's, and if he wants me to pray for those people, then I do so. But I still don't find it an easy process.
I can understand about praying for others.
However, Have mercifully been led of Him over that point a long time ago.
When The Lord shows one a sufficiently intense mirror about one's own flaws, it's much easier to be compassionate and prayerful and forgiving about others--even one's 'enemies.'
Besides, it's the best way to see that they get what they need in terms of discipline. The Lord tends to withhold at least some portions of discipline until we forgive and release them to HIM.
