If Satan cannot conquer us by having us desert the God we love, he will attempt to conquer us by dividing us from others that love the Lord. Only God knows their heart for sure. As children of God, we are to love one another. Love doesn't assume it knows the other's bad motives. Maybe that statement or that action wasn't meant to be unkind after all.
Love gives the benefit of the doubt.
Love will choose to take the statement or action in the best light possible. As here in our chapter, Love will check it out. Love will seek the facts when necessary. The western tribes send ten chiefs with Phinehas, the son of Eleazar the priest, as their leader. They are sent to check out the facts.
