(3.) Those with whom he contends, if they trust in him, shall be relieved, and received into favour, v. 16. He will revive the heart of the contrite ones, for he will not contend for ever. Nothing makes a soul contrite so much as God's contending, and therefore nothing revives it so much as his ceasing his controversy. Here is, [1.] A gracious promise. It is not promised that he will never be angry with his people, for their sins are displeasing to him, or that he will never contend with them, for they must expect the rod; but he will not contend for ever, nor be always wroth. As he is not soon angry, so he is not long angry. He will not always chide. Though he contend with them by convictions of sin, he will not contend for ever; but, instead of the spirit of bondage, they shall receive the Spirit of adoption. He has torn, but he will heal. Though he contend with them by the rebukes of providence, yet the correction shall not last always, shall not last long, shall last no longer than there is need (1 Pet. i. 6), no longer than they can bear, no longer than till it has done its work. Though their whole life be calamitous, yet their end will be peace, and so will their eternity be. [2.] A very compassionate consideration, upon which this promise is grounded: "If I should contend for ever, the spirit would fail before me, ever the souls which I have made." Note, First, God is the Father of spirits, Heb. xii. 9. Those with whom he will not always contend are the souls that he has made, that he gave being to by creation and a new being to by regeneration. Secondly, Though the Lord is for the body, yet he concerns himself chiefly for the souls of his people, that the spirit do not fail, and its graces and comforts. Thirdly, When troubles last long, the spirit even of good men is apt to fail. They are tempted to entertain hard thoughts of God, to think it in vain to serve him; they are ready to put comfort away from them, and to despair of relief, and then the spirit fails. Fourthly, It is in consideration of this that God will not contend for ever; for he will not forsake the work of his own hands nor defeat the purchase of his Son's blood. The reason is taken not from our merit, but from our weakness and infirmity; for he remembers that we are flesh (Ps. lxxviii. 39) and that flesh is weak.
