John 6:27

By the bread which perisheth, is not strictly to be understood bread, but whatsoever is necessary or accommodating to us in this life; all things of this nature are perishing, and perish with the using: nor is all labour as to them forbidden us; for we are to the contrary commanded, In the sweat of our face to eat our bread; and the apostle commandeth, that those that will not labour should not eat; and, Proverbs 31:27, the good woman is commended for not eating the bread of idleness: but excessive labour for these things is forbidden. So also is a first and greater labour for and seeking after them, than after that meat which endureth to everlasting life; under which notion also unquestionably cometh whatsoever is necessary by God's revealed will, that we may have in us the hopes of glory here, and may enter into the actual possession of that glory hereafter. Such as are, first, the knowledge of the gospel; then the believing of it, and the acceptance of that Saviour, and way of salvation, which God hath revealed in it for lost sinners; and that holiness of life which God hath made necessary to it. All which (saith he) I, who am the Son of man, (a name he ordinarily giveth to himself), will give unto you freely. Not that you are to do nothing; no, labour for it; though it be a gift, yet it is a gift upon labour, for all your labour will not procure it; there will be a great deal of free grace seen when you have given all diligence. And Christ must give it; for the Father, in whose hand this life is, hath (as men by their seals use to confirm the commissions they give out to any persons to do any thing for them, and in their name) confirmed Christ as his commissioner, to give out this eternal life to whomsoever he pleaseth.
