Transformation
John and Judas are representatives of those who profess to be Christ's followers. Both these disciples had the same opportunities to study and follow the divine Pattern. Both were closely associated with Jesus and were privileged to listen to His teaching. Each possessed serious defects of character; and each had access to the divine grace that transforms character. But while one in humility was learning of Jesus, the other revealed that he was not a doer of the word, but a hearer only. One, daily dying to self and overcoming sin, was sanctified through the truth; the other, resisting the transforming power of grace and indulging selfish desires, was brought into bondage to Satan.
Such transformation of character as is seen in the life of John is ever the result of communion with Christ. There may be marked defects in the character of an individual, yet when he becomes a true disciple of Christ, the power of divine grace transforms and sanctifies him. Beholding as in a glass the glory of the Lord, he is changed from glory to glory, until he is like Him whom he adores.
John was a teacher of holiness, and in his letters to the church he laid down unerring rules for the conduct of Christians. "Every man that hath this hope in him," he wrote, "purifieth himself, even as He is pure." "He that saith he abideth in Him ought himself also so to walk, even as He walked." 1 John 3:3; 2:6. He taught that the Christian must be pure in heart and life. Never should he be satisfied with an empty profession. As God is holy in His sphere, so fallen man, through faith in Christ, is to be holy in his sphere.
