Let me exhort you to take this seriously. It is not to be understood as mere Bible teaching to be stored away in the mind along with an inert mass of other doctrines. It is a marker on the road to greener pastures, a path chiseled against the steep sides of the mount of God. We dare not try to by-pass it if we would follow on in this holy pursuit. We must ascend a step at a time. If we refuse one step we bring our progress to an end. As is frequently true, this New Testament principle of spiritual life finds its best illustration in the Old Testament. In the story of Abraham and Isaac we have a dramatic picture of the surrendered life as well as an excellent commentary on the first Beatitude. Abraham was old when Isaac was born, old enough indeed to have been his grandfather, and the child became at once the delight and idol of his heart. From that moment when he first stooped to take the tiny form awkwardly in his arms he was an eager love slave of his son. God went out of His way to comment on the strength of this affection. And it is not hard to understand. The baby represented everything sacred to his father's heart: the promises of God, the covenants, the hopes of the years and the long messianic dream. As he watched him grow from babyhood to young manhood the heart of the old man was knit closer and closer with the life of his son, till at last the relationship bordered upon the perilous. It was then that God stepped in to save both father and son from the consequences of an uncleansed love. "Take now thy son," said God to Abraham, "thine only son Isaac, whom thou lovest, and get thee into the land of Moriah; and offer him there for a burnt-offering upon one of the mountains which I will tell thee of." The sacred writer spares us a close-up of the agony that night on the slopes near Beersheba when the aged man had it out with his God, but respectful imagination may view in awe the bent form and convulsive wrestling alone under the stars. Possibly not again until a Greater than Abraham wrestled in the Garden of Gethsemane did such mortal pain visit a human soul. If only the man himself might have been allowed to die. That would have been easier a thousand times, for he was old now, and to die would have been no great ordeal for one who had walked so long with God. Besides, it would have been a last sweet pleasure to let his dimming vision rest upon the figure of his stalwart son who would live to carry on the Abrahamic line and fulfill in himself the promises of God made long before in Ur of the Chaldees.
