The "Sons of God" is a term reserved for those, who through being "Peacemakers" during time, are rewarded with an enhanced experience in the Kingdom. Kingdom rewards and their conditions are a major theme in the Sermon on the Mount. Rewards are not to be seen as a periphery doctrine, but a major thrust. The doctrine of glorification is not absolutely positional truth. The purpose of the Gospel of Matthew (and all the Gospels) needs to be understood theologically, not chronologically alone. Dealing with difficult people is a God-given opportunity to be proclaimed as a child of God who became a son of God. Cf. Luke 6:35-36
