2 Cor 1:8-9, 2 Cor 7:5, Phil 3:10-11, Rom 8:17-18, 35-36, 2 Cor 4:16-18
Paul suffered enough to death while preaching the gospel. (2 Cor 1:8-9, 2 Cor 7:5)
2 Cor 1:8 For we would not, brethren, have you ignorant of our trouble which came to us in Asia, that we were pressed out of measure, above strength, insomuch that we despaired even of life: 9 But we had the sentence of death in ourselves, that we should not trust in ourselves, but in God which raiseth the dead:
2 Cor 7:5 For, when we were come into Macedonia, our flesh had no rest, but we were troubled on every side; without were fightings, within were fears.
But Paul rejoiced to share in the sufferings of Christ. (Phil 3:10-11)
Phil 3:10 That I may know him, and the power of his resurrection, and the fellowship of his sufferings, being made conformable unto his death; 11 If by any means I might attain unto the resurrection of the dead.
Even if we die for the gospel, we will be resurrected like Christ. (2 Cor 4:8-11)
2 Cor 4:8 We are troubled on every side, yet not distressed; we are perplexed, but not in despair; 9 Persecuted, but not forsaken; cast down, but not destroyed; 10 Always bearing about in the body the dying of the Lord Jesus, that the life also of Jesus might be made manifest in our body. 11 For we which live are always delivered unto death for Jesus' sake, that the life also of Jesus might be made manifest in our mortal flesh.
Nothing can separate us from the love of Christ. (Rom 8:35-36)
Rom 8:35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.
The present sufferings for the sake of the gospel cannot be compared with the glory we will receive in the future. (2 Cor 4:16-18, Rom 8:17-18)
2 Cor 4:16 For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day. 17 For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory; 18 While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.
Rom 8:17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together. 18 For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
