I am sorry, but your assertion was that his death a blessing because of suffering. If someone is not suiffering, then no one calls death a blesisng. Early Christians considered it a privilege to suffer and die like the Lord (on the cross). If we are also faith-filled, like they were, then something is amiss.
I originally answered the last one in a somewhat flippant manner. No smiley faces, so how would you know?
Let’s start again. when the Calvinists pray for the sick, what do they expect? For God to change His mind? God does not change His mind. Calvinists pray like David that God will be merciful and like David accept His will.
Or do they praise God for causing the sickness (after all, He is behind tidal waves and hurricanes, why not sickness, right)?Calvinists believe that nothing happens that God does not ordain and everyone is commanded to give thanks to Him in all things. (I am not to wallow in pity of the circumstance but to see my position in Christ and my ministry in the suffering He has ordained for me.)
when a person dies, do Calvinists say "Thank you Lord" and jump from joy?
The “jumping for joy” can only happen if a Calvinist has reason to believe that the person who died possessed belief in Jesus Christ as their Savior; the Calvinist believes it is far better to be with the Lord than to be here. A Calvinist does not joy in the death of a nonbeliever just as God does not.
Is a Calvinist perfect? No. Only the Godman is perfect.
