To “punish” someone after they are sorry for their sins & have repented is “unjust”.
A local church here did just that. If God followed that principle, then all believers may have to spend some time in hell even if they have repented (the absurdity of this non-Biblical principle is obvious).
That’s in line with the thief’s intention to “destroy” others while thinking themselves to be “justified”.
“‘The thief doth not come, except that he may steal, and kill, and destroy; I came that they may have life, and may have [it] abundantly.” – Lord Jesus Christ in (John 10:10)
Such immature actions only proves “who they really are” and not in any way “Who Lord Jesus is”.
