1. That a believer may wait long before he attains it: this appears from what is matter of daily experience and observation. The sovereignty of God discovers itself herein, as much as it does when he makes the ordinances effectual to salvation, in giving converting grace unto those who attend upon them. Some are called early to be made partakers of that salvation that is in Christ, others late. The same may be said with respect to God’s giving assurance. Some are favoured with this privilege soon after, or when first they believe; others are like those whom the apostle speaks of, _who, through fear of death, are all their life-time subject to bondage_, Heb. ii. 15. Many have often enquired into the state of their souls, that cannot discern any marks or evidences of grace in themselves; whose conversation is such, that others cannot but conclude them to be true believers; their spirits are deprest, doubts and fears prevail, and tend to make their lives very uncomfortable; they wait and pray for the evidence and sense of God’s love to them, but cannot immediately find it: this the Psalmist speaks of, either in his own person, or thereby represents the case of many who had the truth of grace, but not the assurance thereof, when he says, _O Lord God of my salvation, I have cried day and night before thee; I am afflicted and ready to die from my youth up; while I suffer thy terrors I am distracted_, Psal. lxxxviii. compared with the xv. God suffers it to be thus with them for wise ends. Hereby he lets them know, that assurance of his love is a special gift and work of the Spirit; without which they remain destitute of it, and cannot take comfort, either from their former or present experiences. 2. They who once enjoyed assurance, may have it weakened and intermitted; whether it may be entirely lost will be considered under a following head, when we speak concerning the supports that believers have, and how far they are kept hereby from sinking into utter despair: it is one thing to fall from the truth of grace, another thing to lose the comfortable sense thereof. The joy of faith may be suspended, when the acts and habits of faith remain firm and unshaken. The brightest morning may afterwards be followed with clouds and tempests; even so our clearest discoveries of our interest in the love of God may be followed with the withdrawment of the light of his countenance, and we be left under many discouraging circumstances concerning our state, having lost the assurance we once had.
