The young Covenanters in those days confronted severest conditions and learned hardest lessons in discipleship. Sometimes they had to forsake father and mother to prove themselves worthy of Christ. Andrew Forsyth, verging on manhood, was required to drink this bitter cup. The family had not yet espoused the Covenanted cause. One day Andrew was entrusted with a flock of sheep for the market. He was over night on the way. As he lay that night guarding his sheep in the field, he heard solemn music. Following the sound, he came to a moss-hag, where a group of Covenanters were worshiping God. A moss-hag is a cut on the hillside, formed by frost and rain; and overhung with moss, heather, and other growths. In such places the pursued Covenanters often hid themselves. The cold grotto was their house; the damp earth their bed; the hole cut out of the hill without hands their sanctuary. Andrew listened with breathless interest. They were singing a Psalm of David. Then followed an earnest prayer. Tie could not endure the suspense, but revealed himself to the little company. They received him gladly, and spent hours talking of Christ, His precious blood, His amazing love, His royal glory, and His unrivalled supremacy. Andrew was a Covenanter when he went home. His father was angry, his mother was sorry, and he had to leave. In a distant moor he made himself a bed under a booth of heather and moss, and supported himself by working for the neighboring shepherds. The dragoons heard of his affiliation with the Covenanters, and were quickly on his path; his life was ever in danger. One day they fired on him, but he escaped and reached his mossy den, carrying a bullet wound received from their fire. There he lay several days, suffering, bleeding, hungry, lonely, and helpless, yet full of peace and joy in the Lord. Often did he think of his father's house, and his mother's love; of the gentle hands that had in other days smoothed his bed and made his bread; yet his heart bloomed with thoughts of the love of Jesus Christ and His sweet promises. His religion had cost much, but he never regretted the bargain by which he had lost the world and gained his soul. At length a shepherd found him, and kindly ministered to his wants. This good boy lived to be an old man, whose grey hair was a crown of glory.
