But always be aware of human limitations. There aren't any 300-y-o humans running around loose anywhere. This is because of the human flaw of sin, that Adam and Eve started among people. We all have it because, if no other reason, their sin was a genetic disorder they passed on to all of us. | Jesus Christ, the son of God, and also a man, took the punishment for all sins of everybody, when He suffered and died on the cross. He sealed it when He arose from the dead on the third day. It's His strength that we all use to do great and good things. But it is the believers in the Jesus-salvation who will rise from death (just like Jesus did) at the last day, to live in joy with God forever.
