Sins of will and sins of frailty.

"When ye turn to the right hand, and when ye turn to the left." This is an evident recognition of the infirmities and wanderings of those who do, of set purpose of heart, mean to serve God. The verse is a gracious assurance that, in such times of frailty, God's people shall have due warning and correction. We may take as types of the two kinds of sin—sins of will and sins of frailty—the two persons who were present to the mind of Christ when he spoke as in ; and these two persons will illustrate the classes who were in the mind of Isaiah when he gave the warning of the text—the boldly willful who persisted in the policy of seeking aid from Egypt, and the frail' ones whose faith faltered under the pressure of the anxiety of the times and the delay of the Divine intervention. They were swayed to this side or to that, but, nevertheless, tried hard to keep steadily, Piglet on.

I. JUDAS, TYPE OF THOSE WHO ARE HEART-WRONG, INSINCERE, RULED BY CONSIDERATIONS OF SELF-INTEREST. There are no minute details given of the process of Judas's apostasy. There was, indeed, nothing unusual about it. The covetous spirit made him connect himself with Christ chiefly for personal ends. The essential thing in any one who unites with Christ is surrender of self and self-will, and this surrender Judas never made. The point, however, to be specially dwelt on here is that his great sin was a matter of will, plan, resolve, determination. He did not drift into it; he was not enticed into it; he was not taken at unawares: he schemed it; he willed it; the guilt of it fully rested on him. Whenever men sin with their wills and openly, they must come under the crushings of Divine judgment. Sins of will are rebellions that must be mastered. The distinction between sins of will and. sins of frailty may be further shown in King Saul and King David.

II. PETER, TYPE OF THE SINCERE BUT FAULTY AND FRAIL. Compare David. Peter was hasty, impulsive, uncertain, sometimes even weak. "The spirit was willing, but the flesh was weak." lie swayed now to this side, and now to that, and needed just such warnings as are provided in the above text. The Apostle John urges on those who are sincere Christians, that if they "say they have no sin, they deceive themselves, and the truth is not in them." And these, which at first are "goings aside," "frailties," will soon grow to become" willfulnesses, "if they are not checked and corrected. Therefore may we rejoice in God, and assure our hearts in his promise that the voice shall call us back when our feet incline to wander to the right or the left.—R.T.
