I. Here is an invitation given to backsliding Israel, and in them to the backsliding Gentiles, to return unto God, the God from whom they had revolted (v. 12): Return, thou backsliding Israel. And again (v. 14): "Turn, O backsliding children! repent of your backslidings, return to your allegiance, come back to that good way which you have missed and out of which you have turned aside." Pursuant to this invitation, 1. They are encouraged to return. "Repent, and be converted, and your sins shall be blotted out, Acts iii. 19. You have incurred God's displeasure, but return to me, and I will not cause my anger to fall upon you." God's anger is ready to fall upon sinners, as a lion falls on his prey, and there is none to deliver, as a mountain of lead falling on them, to sink them past recovery into the lowest hell. But if they repent it shall be turned away, Isa. xii. 1. I will not keep my anger for ever, but will be reconciled, for I am merciful. We that are sinful were for ever undone if God were not merciful; but the goodness of his nature encourages us to hope that, if we by repentance undo what we have done against him, he will by a pardon unsay what he has said against us. 2. They are directed how to return (v. 13): "Only acknowledge thy iniquity, own thyself in a fault and thereby take shame to thyself and give glory to God." I will not keep my anger for ever (that is a previous promise); you shall be delivered form that anger of God which is everlasting, from the wrath to come; but upon what terms? Very easy and reasonable ones. Only acknowledge thy sins. If we confess our sins, he is faithful and just to forgive them. This will aggravate the condemnation of sinners, that the terms of pardon and peace were brought so low, and yet they would not come up to them. If the prophet had told thee to do some great thing wouldst thou not have done it? How much more when he says, Only acknowledge thy iniquity? 2 Kings v. 13. In confessing sin, (1.) We must own the corruption of our nature: Acknowledge thy iniquity, the perverseness and irregularity of thy nature. (2.) We must own our actual sins: "That thou hast transgressed against the Lord thy God, hast affronted him and offended him." (3.) We must own the multitude of our transgressions: "That thou hast scattered thy ways to the strangers, run hither and thither in pursuit of thy idols, under every green tree. Wherever thou hast rambled thou hast left behind thee the marks of thy folly." (4.) We must aggravate our sin from the disobedience that there is in it to the divine law. The sinfulness of sin is the worst thing in it: "You have not obeyed my voice; acknowledge that, and let that humble you more than any thing else."
