This priceless treasure we hold, so to speak, in a common earthenware jar—to show that the splendid power of it belongs to God and not to us. 2 Corinthians 4:7, Phillips.
All the disciples had serious faults when Jesus called them to His service. Even John, who came into closest association with the meek and lowly One, was not himself naturally meek and yielding. He and his brother were called “the sons of thunder.” While they were with Jesus, any slight shown to Him aroused their indignation and combativeness. Evil temper, revenge, the spirit of criticism, were all in the beloved disciple. He was proud, and ambitious to be first in the kingdom of God. But day by day, in contrast with his own violent spirit, he beheld the tenderness and forbearance of Jesus, and heard His lessons of humility and patience. He opened his heart to the divine influence, and became not only a hearer but a doer of the Saviour's words. Self was hid in Christ. He learned to wear the yoke of Christ and to bear His burden.
Jesus reproved His disciples, He warned and cautioned them; but John and his brethren did not leave Him; they chose Jesus, notwithstanding the reproofs. The Saviour did not withdraw from them because of their weakness and errors. They continued to the end to share His trials and to learn the lessons of His life. By beholding Christ, they became transformed in character....
As His representatives among men, Christ does not choose angels who have never fallen, but human beings, men of like passions with those they seek to save....
Having been in peril themselves, they are acquainted with the dangers and difficulties of the way, and for this reason are called to reach out for others in like peril. There are souls perplexed with doubt, burdened with infirmities, weak in faith, and unable to grasp the Unseen; but a friend whom they can see, coming to them in Christ's stead, can be a connecting link to fasten their trembling faith upon Christ.
We are to be laborers together with the heavenly angels in presenting Jesus to the world.18Ibid., 295-297.
