Um, Jesus didn’t have a TEMPORARY body, you know? He has that same body right now. Glorified, but not completely different. He didn’t suffer with a ‘temporary’ body and then throw it away to be pure Spirit.
And 'it only lasted a few hours"?
Tell you what. When you become God (just try to even imagine it --you are all powerful, all knowing, all good), you go ahead and just for a few measly years tie yourself to a ‘human body’ which you will then KEEP forever. Be human, subject to human ills. . .you, the one who MADE the UNIVERSE, let yourself become a human and subject yourself to first your parents and then to your elders, your boss, etc. Then suffer and die --not for yourself. Not even for good people. Suffer and die for people who have lied, cheated, stolen, killed, tortured, raped. . .then go down to purgatory and one-on-one to every soul there and proclaim what you have done–then come back on earth for 40 days and try to get the people who let you down know that you’re still going to help them --and then go back to Heaven, and WAIT and watch those people and see how FEW of them listen or care about what you have done for them,
And then tell me how ‘easy’ it was for you to do.
As for the 'pain?" Crucifixion is no fun thing. We all overestimate our capacity to handle physical pain until we actually suffer it. And we’re just ‘regular’ humans. Imagine if you have NEVER in a thousand bajillion lifetimes of experience ever suffered physical pain --and then you not only suffer it, you suffer an extreme amount of it --and all for people who aren’t even GRATEFUL.
Lord Jesus, forgive our ingratitude and our selfishness.
