We never know where we may be led by jealousy and malice. One of the striking features of this incident is the rapidity with which small sins generate great ones. When Cain went in the joy of harvest and offered his first fruits no thought could be further from his mind than murder. It may have come as suddenly on himself as on the unsuspecting Abel, but the germ was in him. Great sins are not so sudden as they seem. Familiarity with evil thought ripens us for evil action; and a moment of passion, an hour's loss of self-control, a tempting occasion, may hurry us into irremediable evil. And even though this does not happen, envious, uncharitable, and malicious thoughts make our offerings as distasteful as Cain's. He that loveth not his brother knoweth not God. First be reconciled to thy brother, says our Lord, and then come and offer thy gift. Other truths are incidentally taught in this narrative. (1) The acceptance of the offering depends on the acceptance of the offerer. God had respect to Abel and his offering--the man first and then the offering. God looks through the offering to the state of soul from which it proceeds; or even, as the words would indicate, sees the soul first and judges and treats the offering according to the inward disposition. God does not judge of what you are by what you say to Him or do for Him, but He judges what you say to Him and do for Him by what you are. "By _faith_" says a New Testament writer, "Abel offered a more acceptable sacrifice than Cain." He had the faith which enabled him to believe that God is, and that He is a rewarder of them that diligently seek Him. His attitude towards God was sound; his life was a diligent seeking to please God; and from all such persons God gladly receives acknowledgment. When the offering is the true expression of the soul's gratitude, love, devotedness, then it is acceptable. When it is a merely external offering, that rather veils than expresses the real feeling; when it is not vivified and rendered significant by any spiritual act on the part of the worshipper, it is plainly of no effect.
