Having (Ti2 1:13, Ti2 1:14) exhorted Timothy to hold fast, I. He mentions the apostasy of many from the doctrine of Christ, Ti2 1:15. It seems, in the best and purest ages of the church, there were those that had embraced the Christian faith, and yet afterwards revolted from it, nay, there were many such. He does not say that they had turned away from the doctrine of Christ (though it should seem they had) but they had turned away from him, they had turned their backs upon him, and disowned him in the time of his distress. And should we wonder at it, when many turned their backs on a much better than Paul? I mean the Lord Jesus Christ, Joh 6:66. II. He mentions the constancy of one that adhered to him, namely, Onesiphorus: For he often refreshed me, and was not ashamed of my chain, Ti2 1:16. Observe, 1. What kindness Onesiphorus had shown to Paul: he refreshed him, he often refreshed him with his letters, and counsels, and comforts, and he was not ashamed of his chains. He was not ashamed of him, not withstanding the disgrace he was now under. He was kind to him not once or twice, but often; not only when he was at Ephesus among his own friends, but when Onesiphorus was at Rome; he took care to seek Paul out very diligently, and found him, Ti2 1:17. Observe, A good man will seek opportunities of doing good, and will not shun any that offer. At Ephesus he had ministered to him, and been very kind to him: Timothy knew it. 2. How Paul returns his kindness, Ti2 1:16-18. He that receives a prophet shall have a prophet's reward. He repays him with his prayers: The Lord give mercy to Onesiphorus. It is probable that Onesiphorus was now absent from home, and in company with Paul; Paul therefore prays that his house might be kept during his absence. Though the papists will have it that he was now dead; and, from Paul's praying for him that he might find mercy, they conclude the warrantableness of praying for the dead; but who told them that Onesiphorus was dead? And can it be safe to ground a doctrine and practice of such importance on a mere supposition and very great uncertainty? III. He prays for Onesiphorus himself, as well as for his house: That he may find mercy in that day, in the day of death and of judgment, when Christ will account all the good offices done to his poor members as done to himself. Observe, 1. The day of death and judgment is an awful day, and may be emphatically called that day. 2. We need desire no more to make us happy than to find mercy of the Lord in that day, when those that have shown no mercy will have judgment without mercy. 3. The best Christians will want mercy in that day; looking for the mercy of our Lord Jesus Christ, Jde 1:21. 4. If you would have mercy then, you must seek for it now of the Lord. 5. It is of and from the Lord that we must have mercy; for, unless the Lord has mercy on us, in vain will be the pity and compassion of men or angels. 6. We are to seek and ask for mercy of the Lord, who is the giver and bestower of it; for the Lord Jesus Christ has satisfied justice, that mercy might be displayed. We are to come to a throne of grace, that we may obtain mercy, and find grace to help in the time of need. 7. The best thing we can seek, either for ourselves or our friends, is that the Lord will grant to them that they may find mercy of the Lord in that day, when they must pass our of time into eternity, and exchange this world for the other, and appear before the judgment-seat of Christ: the Lord then grant unto all of us that we may find mercy of the Lord in that day.
