May God, Make You Worthy of His Calling"
The blasphemous notion suggested by some that Christians need to forgive God for allowing them to suffer completely misses the point. According to that view, believers suffer because though God is well meaning, He is unable to work out all of life’s contingencies. Nothing could be further from the truth. For the reasons noted above, suffering is part of God’s wise, loving, perfect, sovereign plan for His children; they “suffer according to the will of God” (1 Peter 4:19
Perseverance (hupomonē) is not resigned, stoic acquiescence but patient, courageous enduring of trouble. The word literally speaks of “remaining under,” or sustaining hope under difficulty. It is not a grim waiting but a joyful hoping
Believers can face trials joyfully, knowing that God is equipping them for eternal glory. Leon Morris insightfully observes:
The New Testament does not look on suffering in quite the same way as do most modern people. To us it is in itself an evil, something to be avoided at all costs. Now while the New Testament does not gloss over this aspect of suffering it does not lose sight either of the fact that in the good providence of God suffering is often the means of working out God’s eternal purpose. It develops in the sufferers qualities of character. It teaches valuable lessons. Suffering is not thought of as something which may possibly be avoided by the Christian. For him it is inevitable. He is ordained to it (1 Thess. 3:3). He must live out his life and develop his Christian character in a world which is dominated by non-Christian ideas. His faith is not some fragile thing, to be kept in a kind of spiritual cotton wool, insulated from all shocks. It is robust. It is to be manifested in the fires of trouble, and in the furnace of affliction. And not only is it to be manifested there, but in part at any rate, it is to be fashioned in such places. The very troubles and afflictions which the world heaps on the believer become, under God, the means of making him what he ought to be. Suffering, when we have come to regard it in this light, is not to be thought of as evidence that God has forsaken us, but as evidence that God is with us. Paul can rejoice that he fills up “that which is lacking of the afflictions of Christ in my flesh for his body’s sake, which is the church” (Col. 1:24). Such suffering is a vivid token of the presence of God. (The First and Second Epistles to the Thessalonians, The New International Commentary on the New Testament [Grand Rapids: Eerdmans, 1989], 197–98)
The return of Jesus Christ is therefore the climax of all redemptive history and brings God’s purpose to culmination. Paul reminded the Thessalonians of this great hope to encourage them to stand firm despite the severe persecution they were undergoing. Their hope—like that of all suffering Christians—was that Jesus would return and bring them relief.
Currently, the glory of our Lord is hidden, and most people believe He is dead (cf. Acts 25:19). Even believers do not experience the fullness of His glorious presence, for as Peter writes, “Though you have not seen Him, you love Him, and though you do not see Him now, but believe in Him, you greatly rejoice with joy inexpressible and full of glory” (1 Peter 1:8). But the day is coming when He will be revealed, both to believers and to unbelievers
God’s retribution, however, is not like the unruly, hostile, selfish, sinful passion that causes people to retaliate against others, since “the God who inflicts wrath is not unrighteous” (Rom. 3:5). But because sinful humans are not perfectly holy, completely just, and omniscient, they cannot render perfect judgment. Therefore, God reserves vengeance for Himself. In the Sermon on the Mount, Jesus forbade personal vengeance (Matt. 5:38–48), and Paul wrote in Romans 12:19, “Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, ‘Vengeance is Mine, I will repay,’ says the Lord” (cf. Deut. 32:35; Isa. 66:15–16; Heb. 10:30).
