How ignorant of the scriptures they are! We are parts - members - of Jesus’ body. As such, we are guaranteed suffering. Didn’t Jesus mention a “cross”? That is not the crown of glory! Not yet. Ask them to explain why we still suffer, if Jesus took it all? This line of reasoning does not comport with reality and has made more than one believer into an atheist. Sadly, this is rightfully so. Their theology is both irrational as well as ignorant. They may be loud talkers but they are not deep thinkers.
The readings of Paul - even Paul’s conversion - show that suffering has redemptive value. If we do not suffer, we can expect no crown of glory. The Lord told Ananias, then Paul directly that Saul/Paul would have to suffer for the Name. A lifetime of suffering as penance for having persecuted the Church; for having stood by, and approving of the murder of Stephen the Deacon (Acts 6).
It sounds like your friends ascribe to the doctrine of “Public Assistance Christianity” in which someone else pays and they simply wait for the benefits to arrive. That produces a lazy, even a dead faith. James 2 is very instructive here.
How sad it is that those who live by Paul ignore the vast majority of the content that he wrote. Without knowing it, their hope is not so much in Christ as it is in the Catholic Church’s doctrine of invincible ignorance. They are certainly worthy of prayer.
