2 Cor 4:10-11, Phil 3:10, Col 1:24, 1 Pt 4:13, 1 Cor 4:9, 11-13
Paul suffered many hardships while preaching the gospel. He even suffered enough to die. But all those sufferings were Christ's remaining suffering. (2 Cor 1:5-10, 2 Cor 4:10-11, 1 Cor 4:9,11-13)
2 Cor 1:5 For as the sufferings of Christ abound in us, so our consolation also aboundeth by Christ. 6 And whether we be afflicted, it is for your consolation and salvation, which is effectual in the enduring of the same sufferings which we also suffer: or whether we be comforted, it is for your consolation and salvation. 7 And our hope of you is stedfast, knowing, that as ye are partakers of the sufferings, so shall ye be also of the consolation. 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: 10 Who delivered us from so great a death, and doth deliver: in whom we trust that he will yet deliver us;
2 Cor 4:10 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.
1 Cor 4:9 For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men. 11 Even unto this present hour we both hunger, and thirst, and are naked, and are buffeted, and have no certain dwellingplace; 12 And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it: 13 Being defamed, we intreat: we are made as the filth of the world, and are the offscouring of all things unto this day.
Paul rejoiced in the suffering he suffered while preaching the gospel and wanted to participate in it. (Phil 3:10, Col 1:24)
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;
Col 1:24 Who now rejoice in my sufferings for you, and fill up that which is behind of the afflictions of Christ in my flesh for his body's sake, which is the church:
Rejoice to the extent that you partake of Christ’s sufferings. (1 Pt 4:13)
1 Pt 4:13 But rejoice, inasmuch as ye are partakers of Christ's sufferings; that, when his glory shall be revealed, ye may be glad also with exceeding joy.
