Adam’s holiness was mutable; God did not determine to keep him. It is otherwise with believers in Christ; God has determined to give them the kingdom (_Luke 12:32_). Yet this keeping by God, which we call sanctification, is accompanied and followed by a keeping of himself on the part of the believer, which we call perseverance. The former is alluded to in _John 17:11, 12_—“_keep them in thy name.... I kept them in thy name.... I guarded them, and not one of them perished, but the son of perdition_”; the latter is alluded to in _1 John 5:18_—“_he that was __ begotten of God keepeth himself._” Both are expressed in _Jude 21, 24_—“_Keep yourselves in the love of God.... Now unto him that is able to guard you from stumbling..._” A German treatise on Pastoral Theology is entitled: “Keep What Thou Hast”—an allusion to _2 Tim. 1:14_—“_That good thing which was committed unto thee guard through the Holy Spirit which dwelleth in us._” Not only the pastor, but every believer, has a charge to keep; and the keeping of ourselves is as important a point of Christian doctrine as is the keeping of God. Both are expressed in the motto: _Teneo, Teneor_—the motto on the front of the Y. M. C. A. building in Boston, underneath a stone cross, firmly clasped by two hands. The colored preacher said that “Perseverance means: 1. Take hold; 2. Hold on; 3. Never let go.” Physically, intellectually, morally, spiritually, there is need that we persevere. Paul, in _1 Cor. 9:27_, declares that he smites his body under the eye and makes a slave of it, lest after having preached to others he himself should be rejected; and in _2 Tim. 4:7_, at the end of his career, he rejoices that he has “_kept the faith_.” A. J. Gordon, Ministry of the Spirit, 115—“The Christian is as ‘_a tree planted by the streams of water, that bringeth forth its fruit in its season_’ (_Ps. 1:3_), but to conclude that his growth will be as irresistible as that of the tree, coming as a matter of course simply because he has by regeneration been planted in Christ, is a grave mistake. The disciple is required to be consciously and intelligently active in his own growth, as the tree is not, ‘_to give all diligence to make his calling and election sure_’ (_2 Pet. 1:10_) by surrendering himself to the divine action.” Clarke, Christian Theology, 379—“Man is able to fall, and God is able to keep him from falling; and through the various experiences of life God will so save his child out of all evil that he will be morally incapable of falling.” 1.
