but if the rotten ones are converted to good ones, then they are gotten rid of because they are born again. The old rotten person would then no longer exist.
Many people who are not Christians are still the good ones, IMHO.
Yes anyone can be saved, but they must first want to be saved. You cannot force it on anyone.
If Jesus came back, healed the sick and dying, did more miricles, brought about world peace, ened hunger and poverty, etc. Wouldn't it fix things?
