"Perfecting holiness in the fear of God"

2 Corinthians 7:1 Therefore, having these promises, beloved, let us cleanse ourselves from all filthiness of the flesh and spirit, perfecting holiness in the fear of God.

“by "holiness" is not meant the work of sanctification upon the heart, for that is wholly the work of the Spirit of God, and not of man; he begins it, carries it on, and perfects it of himself; but holiness of life and conversation is here designed, which in conversion the people of God are called unto, and which highly becomes them: and this they are to be "perfecting"; not that a believer is able to live a life of holiness, without sin being in him, or committed by him; this is impossible and impracticable in the present life; but the sense of the word επιτελουντες is, that he is to be carrying on a course of righteousness and holiness to the end; to the end of his life, he is to persevere as in faith, so in holiness; as he is to go on believing in Christ, so he is to go on to live soberly, righteously, and godly, to the end of his days; which requires divine power to preserve him from sin, and keep him from falling; and the grace of God, the strength of Christ, and the assistance of the Spirit, to enable him to perform acts of holiness, and the several duties of religion, and to continue in well doing: all which is to be done, "in the fear of God"; not in a servile slavish fear, a fear of hell and damnation, but in a filial fear, a reverential affection for God, an humble trust in him, and dependence on him, for grace and strength; it is that fear which has God for its author, is a blessing of the new covenant, is implanted in regeneration, and is increased by discoveries of pardoning grace; and it has God for its object, not his wrath and vindictive justice, but his goodness, grace, and mercy. This shows from what principle, and upon what views believers act in a course of righteousness and holiness; not from the fear of hell, nor from the fear of men, or with a view to gain their applause, but as in the sight of God, from a reverential affection to him, a child like fear of him, and with a view to his glory.” - John Gill
