No, there are no such promises. We are actually warned ahead of time to prepare for suffering:
Acts 9:15 But the Lord said to Ananias, “Go! This man [Saul] is my chosen instrument to carry my name before the Gentiles and their kings and before the people of Israel. 16 I will show him how much he must suffer for my name.”
Rom 8:17 Now, if we are children, then we are heirs – heirs of God and co-heirs with Christ, if indeed we share in his sufferings in order that we may also share in His glory.
2 Cor 1:8 We do not want you to be uninformed, brothers, about the hardships we suffered in the province of Asia. We were under great pressure, far beyond our ability to endure, so that we despaired even of life. 9 Indeed, in our hearts we felt the sentence of death. But this happened that we might not rely on ourselves but on God, who raises the dead.
Phil 1:27 Whatever happens, conduct yourselves in a manner worthy of the gospel of Christ. Then, whether I come and see you or only hear about you in my absence, I will know that you stand firm in one spirit, contending as one man for the faith of the gospel 28 without being frightened in any way by those who oppose you. This is a sign to them that they will be destroyed, but that you will be saved – and that by God. 29 For it has been granted to you on behalf of Christ not only to believe on Him, but also to suffer for Him, 30 since you are going through the same struggle you saw I had, and now hear that I still have.
2 Tim 1:3 Endure hardship with us like a good soldier of Christ Jesus. 4 No one serving as a soldier gets involved in civilian affairs – he wants to please his commanding officer.
2 Tim 3:12 Indeed, all who desire to live godly in Christ Jesus will be persecuted.
1 Pet 4:12 Dear friends, do not be surprised at the painful trial you are suffering, as though something strange were happening to you. 13 But rejoice that you participate in the sufferings of Christ, so that you may be overjoyed when His glory is revealed. 14 If you are insulted because of the name of Christ, you are blessed, for the Spirit of glory and of God rests on you. 15 If you suffer, it should not be as a murderer or thief or any other kind of criminal, or even as a meddler. 16 However, if you suffer as a Christian, do not be ashamed, but praise God that you bear that name. 17 For it is time for judgment to begin with the family of God; and if it begins with us, what will the outcome be for those who do not obey the gospel of God? 18 And, “If it is hard for the righteous to be saved, what will become of the ungodly and the sinner?” 19 So, then, those who suffer according to God’s will should commit themselves to their faithful Creator and continue to do good.
What gets us through suffering is faith, pure and simple. Our reward is eternal life, so whatever we go through on earth or how we die, it's good to remember that we are already saved.
