Will we die if we see god if thats the answer i understand but what about this?

A disciple of Christ, Thomas, was a skeptic. He walked with Jesus during his time on earth and physically witnessed with his own eyes certain miracles performed by him such as raising Lazarus from the dead and so forth. However, after the crucifixion, Jesus supposedly rose three days later. Thomas did not believe it was truly him despite being told, prior to the incident by Jesus, that he would rise again in three days. Thomas required physical proof. Jesus allowed him to touch him and feel the wounds in his body to offer proof. Why doesn't god extend the same proof to humans alive today? Those that doubt his existence are no different than Thomas, requiring physical proof and he was a disciple of Jesus himself. If Thomas had been born one generation later, or even living today, he would have burned in hell for all eternity because he would not believe for the lack of physical proof. Paul was born after the death and ascension of Christ. Throughout his life, he did not believe that Jesus was the son of God and even went out of his way to persecute Christians thinking that their religion was a dangerous belief system to practice. Lo and behold a flash of light came out of the sky and Jesus Christ himself appeared to Paul explaining to him that he is actually the one true god. Jesus told him that he was persecuting the followers of the only true faith. From that point on, Paul was a converted Christian. Again, if God was willing to go out of his way to physically prove to Paul that he actually exists, why is this not done today? Why isn't God willing to show those that doubt today the same degree of physical proof? Why should we be any different than Thomas and Paul?
