Those who could not offer a bullock, were to bring a sheep or a goat; and those who were not able to do that, were accepted of God, if they brought a turtle-dove, or a pigeon. Those creatures were chosen for sacrifice which were mild, and gentle, and harmless; to show the innocence and meekness that were in Christ, and that should be in Christians. The offering of the poor was as typical of Christ's atonement as the more costly sacrifices, and expressed as fully repentance, faith, and devotedness to God. We have no excuse, if we refuse the pleasant and reasonable service now required. But we can no more offer the sacrifice of a broken heart, or of praise and thanksgiving, than an Israelite could offer a bullock or a goat, except as God hath first given to us. The more we do in the Lord's service, the greater are our obligations to him, for the will, for the ability, and opportunity. In many things God leaves us to fix what shall be spent in his service, whether of our time or our substance; yet where God's providence has put much into a man's power, scanty offerings will not be accepted, for they are not proper expressions of a willing mind. Let us be devoted in body and soul to his service, whatever he may call us to give, venture, do, or suffer for his sake.
