If you are motivated to be kind to others only because of the promise of "eternal life", then are you really striving to be good? That is, you know if you don't do it, you'll end up in eternal torment. A fear-based belief. You are only good because you fear punishment. Compliance out of fear. You want to be good only for the reward and to avoid the lakes of fire, not because it is the right thing to do. Dear one, that is blackmail. So now, keeper of faith, why are you fighting to be good?
