God does kill His unrepentant child . . . God would rather call him home than to allow him to continue to destroy his testimony.
Another verse which contributes to this view is found with the Lord's table in our local churches.
"But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. For this cause many are weak and sickly among you, and many sleep" (I Corinthians 11:28-30).
I believe it has been made clear on this site from previous posts that to 'sleep' is to be dead.
A great concern of mine is for those pastors that allow people to partake in the Lord's table without teaching them the seriousness of the ordinance. In approaching this, sin needs to be confessed and the Blood of Christ applied to the cleansing of their souls.
Some are confused about the issue of eternal security. They say, what if a person continues to sin after they are saved - will they not lose their salvation? God has established borders for many things, including a limit to how much a person can make a mockery of this free gift of salvation. Once it is apparent that the erring child has no intentions of getting right with God, God calls them home.
A study of the shepherd and his sheep comes in handy. The Rod and the staff were the same tool. One end was crooked in order to steer the lamb back on track . . . the other end, the rod, was a sharp point that the shepherd would use to jab it back onto the path. When that was no longer effective, more drastic measures were employed. Simply put, if a lamb continues to get out of formation (the shepherd was personally responsible for any damage one of his animals did to a farmer's land and the only had small paths to walk through) the shepherd would sling a stone and break a leg of the animal. He would carry it until it was healed. If, however, the sheep continues to stray the next stone will be aimed at it's head - to kill it.
The shepherd is a biblical type of the Lord. We are the sheep of His fold.
