When Joseph sees this, his heart warms to them. He may not yet be quite sure of them. A prison-repentance is perhaps scarcely to be trusted. He sees they would for the moment deal differently with him had they the opportunity, and would welcome no one more heartily than himself, whose coming among them had once so exasperated them. Himself keen in his affections, he is deeply moved, and his eyes fill with tears as he witnesses their emotion and grief on his account. Fain would he relieve them from their remorse and apprehension--why, then, does he forbear? Why does he not at this juncture disclose himself? It has been satisfactorily proved that his brethren counted their sale of him the great crime of their life. Their imprisonment has elicited evidence that that crime had taken in their conscience the capital place, the place which a man finds some one sin or series of sins will take, to follow him with its appropriate curse, and hang over his future like a cloud--a sin of which he thinks when any strange thing happens to him, and to which he traces all disaster--a sin so iniquitous that it seems capable of producing any results however grievous, and to which he has so given himself that his life seems to be concentrated there, and he cannot but connect with it all the greater ills that happen to him. Was not this, then, security enough that they would never again perpetrate a crime of like atrocity? Every man who has almost at all observed the history of sin in himself, will say that most certainly it was quite insufficient security against their ever again doing the like. Evidence that a man is conscious of his sin, and, while suffering from its consequences, feels deeply its guilt, is not evidence that his character is altered.
And because we believe men so much more readily than God, and think that they do not require, for form's sake, such needless pledges of a changed character as God seems to demand, it is worth observing that Joseph, moved as he was even to tears, felt that common prudence forbade him to commit himself to his brethren without further evidence of their disposition. They had distinctly acknowledged their guilt, and in his hearing had admitted that the great calamity that had befallen them was no more than they deserved; yet Joseph, judging merely as an intelligent man who had worldly interests depending on his judgment, could not discern enough here to justify him in supposing that his brethren were changed men. And it might sometimes serve to expose the insufficiency of our repentance were clear-seeing men the judges of it, and did they express their opinion of its trustworthiness. We may think that God is needlessly exacting when He requires evidence not only of a changed mind about past sin, but also of such a mind being now in us as will preserve us from future sin; but the truth is, that no man whose common worldly interests were at stake would commit himself to us on any less evidence. God, then, meaning to bring the house of Israel into Egypt in order to make progress in the Divine education He was giving to them, could not introduce them into that land in a state of mind which would negative all the discipline they were there to receive.
These men then had to give evidence that they not only saw, and in some sense repented of, their sin, but also that they had got rid of the evil passion which had led to it. This is what God means by repentance. Our sins are in general not so microscopic that it requires very keen spiritual discernment to perceive them. But to be quite aware of our sin, and to acknowledge it, is not to repent of it. Everything falls short of thorough repentance which does not prevent us from committing the sin anew. We do not so much desire to be accurately informed about our past sins, and to get right views of our past selves; we wish to be no longer sinners, we wish to pass through some process by which we may be separated from that in us which has led us into sin. Such a process there is, for these men passed through it.
