XV. Remember, that by the name of a Christian written in heaven, is intimated that solid, practical _knowledge of Christ_ which is grounded _in faith_, and by which we are transplanted into Christ. From this knowledge flow all the living virtues which the Lord will praise in the great day of retribution. Matt. 25:34, etc. He will then also bring to light all those treasures which we have laid up in heaven (1 Tim. 6:19), together with all such works as have been wrought in God. John 3:21. Never has a saint lived upon earth, but he has been particularly eminent in one virtue or other; and this virtue shall never be forgotten. Ps. 112:6. Whether it be faith, love, mercy, patience, or any other virtue in the practice of which he has been so conspicuous, it shall make up that eternal name which is written in heaven. Rev. 2:17; 3:12. This will be the note and character of the saints, and their eternal memorial before God. But of this, more shall be said in Book II. Chapter XLI. The Whole Of Christianity Consists In The Restoration Of The Image Of God In Man, And The Destruction Of The Image Of Satan. _But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord._—2 COR. 3:18. In the _true knowledge_ of Christ, wherein is comprehended that of his Person, offices, benefits, and heavenly and eternal gifts, consists _life everlasting_. John 17:3. This knowledge is kindled in our hearts by the Divine Spirit, and is a new light shining forth with increasing brightness, and passing on from glory to glory. It is like a metallic body, which, by constant polishing, becomes every day more brilliant; or like a tender infant, which, by a daily supply of food, grows up in vigor and strength. No sooner is the righteousness of Christ, through faith, conferred upon a returning sinner, than he is also really born again, and the image of God is daily renewed within him. His spiritual growth, or the renovation of his mind, goes on, however, in a successive manner, from one degree to another, for he has not yet become a “perfect man in Christ.” Eph. 4:13. He is a child for some time; but is continually nourished by the Divine Spirit, and daily brought to a greater conformity with the Lord Jesus Christ.
