Karma is actually a (spiritual law) given a worldly name. Jesus said "With whatever measure you measure to another it will be used to measure back to you"(Matthew 7: 2) God's spiritual law, is enforced and in effect (much like gravity) whether you are a believer or not, the only thing they can stop what you measure to another person coming back to you is repentance. "If we confess our sins He is faithful and just to forgive us our sins and cleanse us of all wrongdoing" (1 John 1:9) This is the reason Jesus taught "Do to others what you would have them do to you" because that's exactly what's going to happen. And because it doesn't come back on us right away, we think we got away with it, but sooner or later what we did to others will knock on our door, if we do not repent. Serious food for thought about how we treat one another
