Biblical question for ONLY Christians!?

God really means everything that he says. In the New Testament though, Jesus came to die for our sins, ushering in a new era of forgiveness and compassion. The idea is that no one is perfect, and we all have to wait until judgement day for any justice because one sinner can't condemn another sinner. It would just be hypocrisy. So if someone must die for their sins, they have to wait until judgement day. We, as humans, should not kill them.
