...could a loving parent justify killing their infant child in order to ensure that their child spends forever in Heaven?
Conversely, is it reckless and unloving for a parent to allow their offspring to reach the age of accountability and risk that they will spend forever being tortured by Jesus in Hell?
These ridiculous questions demonstrate the illogical doctrine of forever punishment. Right?
God would not, will not punish infants, small children, the mentally handicapped, etc. BUT I believe God will do what He said He would.
Jeremiah 13:11-14
(11) For as the girdle cleaveth to the loins of a man, so have I caused to cleave unto me the whole house of Israel and the whole house of Judah, saith the LORD; that they might be unto me for a people, and for a name, and for a praise, and for a glory: but they would not hear.

Matthew 7:21-23
(21) Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
(22) Many [not a few] will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
(23) And then will I [Jesus] profess unto them, I never knew you: depart from me, ye that work iniquity.
When Jesus says "Never" He does not mean someday by and by.
