2 Corinthians 8:5

And this they did not as we hoped
All this was unexpected by the apostles, who knew their great affliction and deep poverty, and therefore could not have hoped for such a collection from them; or that they would have desired the apostle to have ministered it for them:

but first gave their own selves to the Lord, and unto us by the will
of God;
the sense of which is not barely, or only, that they committed themselves to the care of Providence in all their afflictions and poverty, trusting in God that he would provide for them for time to come, and therefore even in their strait circumstances gave liberally; and were so much under the direction of the apostles, God so disposing their minds, that they were willing to do or give anything that they should say was proper; yea, were very willing that some of their number should leave their habitations and families to accompany them, in forwarding this good work elsewhere: but the apostle seems to have respect to what these persons did at first conversion, when they gave themselves to Christ, to be saved by him, and him alone; and to serve him to the uttermost, in everything, he should signify to be his will; and when they joined themselves to the churches of Christ, and put themselves under the care, government, and direction of the apostles, who were over the churches in the Lord: and therefore though what the members of these churches collected, was very wonderful and beyond expectation; yet when it is considered that these persons had long ago given their whole selves, their all to Christ, had committed all into his hands, and devoted themselves entirely to his service; and had declared their subjection to his ministers as servants under him, and to his word and ordinances as ministered by them; it need not be so much wondered at, that they should be so liberal in giving away their worldly substance for the relief of Christ's poor members, when they had given their precious souls, their immortal all, and had committed the salvation of them entirely to him. Giving themselves to Christ, in this sense, supposes that they had a true sight and apprehension of their state and condition by nature, how sinful they were, and lost and undone in themselves; that they were destitute of a righteousness, and unable to obtain one by the works of the law; that they were in hopeless and helpless circumstances, as considered in themselves; that they were diseased from head to foot, and could not cure themselves; that they were dead in law, and liable to the curse and condemnation of it; for till men see themselves in such a case they will never give themselves to Christ, or betake themselves to him to be saved by him. Moreover, this supposes some knowledge of him as God's ordinance for salvation, as the Saviour of the Father's appointing and sending; of him, as having effected it by his obedience and death; of his being the only Saviour, a suitable one, both able and willing to save to the uttermost, even the chief of sinners that come to God by him. It is expressive of faith in Christ; of seeing the Son and the fulness of grace and salvation in him, and of going to him for it; of staying, resting, leaning, and relying upon him, venturing on him, committing all into his hands, and trusting him with all and for all. It denotes subjection to him, as their husband, to whom they give themselves as his spouse and bride, and consent to be the Lord's in a conjugal relation; and submission to him in all his offices, as a prophet to be taught and instructed by him, as a priest to be washed in his blood, and justified by his righteousness, to which they heartily submit, and as their Lord and King to the sceptre of his kingdom, the laws of his house, and ordinances of his Gospel; for they are made a willing people, not only to be saved by him, but to serve him in body and soul, and with all they have; as it is but right they should, since he has given himself, his all, for them. Giving themselves up to the apostles, signifies not a surrender of themselves to them as lords over God's heritage, to be governed and ruled over in a tyrannical and arbitrary way; but a submitting of themselves to them, as Christ's servants set over them in the Lord, whilst they minister the word and administer the ordinances, according to the will of Christ; owning them as their fathers, or instructors, and guides, and as watchmen and overseers placed in and over the churches, for their spiritual welfare: all which is,

by the will of God:
as that poor sensible sinners should give up themselves to Christ, to be saved by him, and serve him; and that they should join themselves to the churches, and be subject to the care, teachings, and government of his servants in his house.
