When I see or hear of another believer sin, it affects me deeply. I am very grieved and troubled in my spirit. Here is why. It is like they despise the sacrifice that Jesus made for them. They are saying in essence that what Jesus did for them, suffering & dying, has little meaning to them. And when it has less and less meaning to them, it also becomes less and less real. That saddens me too.
Please Christians. Just because God has extended grace and forgiveness, don't think that it cost Him nothing. It was very real what Jesus went through.
