Jesus recognized the potential problem of a easy believism as indicated in John 8:30-31, he gave us the Sermon on the Mount. That addresses our heart issue. MacArthur does a wonderful job in the progression of the Beatitudes. It is not after about what men can do but what men are. Because what flows from the heart, is the motive, and the good works that are by faith in not of our own. I was surprised that the Sermon on the Mount is the best means of evangelism but when you think about it, a life lived broken in spirit, mourning over sin, Mercy received, mercy given, thirst and a hunger for righteouness, peacemaker to bring the lost to the Lord would only mean that we have denied self and live a life totally for the Lord. Each blessings is described with scripture. I had one issue with the peacemaker aspect of the teaching but it was minor. A great and reflective read that will check your heart and move you closer to the heart of God.
