The rapidly approaching end of the age is witnessing a tremendous increase in the activity of the powers of darkness. These conditions are reacting strongly upon the great ministry of Christ’s Church. No longer are these concerned about the lost souls which wander in darkness; their thought is centered on raising their social status and meeting their intellectual and physical needs. They seek, in their own jargon, to build a better world. But the world they envision is one without a Savior. There are few subjects relating to the Christian life concerning which there is so little exact knowledge as that of the Authority of the Believer. This is not because such authority is the property only of a few elect souls. On the contrary, it is the possession of every true child of God. It is one of the all things received in Christ. Its reception dates from the soul’s contact with Calvary. John MacMillan was a Canadian Presbyterian businessman who became involved with ministry to Chinese and Jewish people in Toronto. Ordained at the age of 49, MacMillan and his wife traveled to China as missionaries with The Christian and Missionary Alliance. He later became Field Director of the Christian and Missionary Alliance in the Philippines.
