Every one that hath this hope, that is, the hope of seeing and enjoying Christ in glory, he now endeavours to purify himself, according to the pattern and copy which Christ hath set before him, labouring to imitate it, though he cannot reach it.
Observe here, 1. The character of a Christian by this hope, every man that hath this hope in him.
Learn, That a Christian is a person of high hopes, and raised expectations, as to future blessedness; the author of this hope is God; the object of this hope is some future good promised and expected; the grounds of this hope are the promise and oath of God, the purchase and undertaking of Christ, and the sanctifying work of the Spirit, in and upon his soul.
Observe, 2. A description of this hope by its inseparable effect, it purifies the Christian; he that has this hope purifies himself; where it is implied,
1. That sin is a pollution which we must be purified from. 2. That the holiest of saints here on earth, are not perfectly purified from this pollution, but are daily endeavouring to purify themselves more and more.
Observe, 3. The pattern after which the sincere Christian doth conform in this work of purification, and that is Christ: he purifies himself, even as he is pure; intimating, that the Lord Jesus Christ was a perfect pattern of purity; and that it is the Christian's duty to eye this pattern, and to endeavour to conform himself thereunto, by purifying himself, even as Christ is pure.
