"I don't care home many women and children he shot and cut up with scissors. I'm a Christian, who am I to judge this man?"
Being a christian has nothing to do with this, you only "judge" a person when you speculate, when you don't know everything about what happened....in other words, gossiping can cause false accusations (judgements). BUT, if you've seen the person on the corner selling crack, killing people, cutting up people with scissors then saying "HE/SHE'S GUILTY" isn't judging. "You shall know them by their fruits."
Luke 13:6-9 Can be applied to this where the gardener/dresser is you on the jury.
This all falls under reaping what you sow too. Ofcourse we aren't suppose to give an eye for an eye, or that type of thing, but we also have to live by the rules of the land. It's said many times that the bible is "first natural then spiritual", so if we're suppose to obey God's laws, we're suppose to obey man's laws too....or suffer the consequenses (reap what we sow.)
I'm in the military, many people try to use the "thou shalt not kill" commandment to get away from doing their duty. Don't they know that God himself sent His people to kill many times, not to mention doing it himself. In the military, we have a job, I don't necessarily have to kill people myself, but I support the infantry people who do, by making sure they're supplied with the goods to do their job. However, if I found myself in between crossfire, I wouldn't hessitate to pull the trigger.
Going back to what was said: God put us, christians here to be the leaders of the world in the first place. If we can't judge them correctly, and fairly, who can? A person can be forgiven, but that doesn't take away the fact that they have to pay for what they did. Paul killed/helped kill christians. He became one of the greatest, if not the greatest apostle. He still reaped what he sowed. On the cross next to Jesus, there was a thief. He accepted Jesus just before he died, and Jesus himself said the man was going to make it to paradise. I bet the people on the ground thought he was going to rot in hell.
In conclusion, if you do so happen to find yourself on a jury. It's ok. Just make sure you pray that person gets himself right before his life ends.
