Here are a few Scriptural references to show the idea of an 'all-loving God' is a fallacy taught by Rome, the pagan capital of the world.
“These six things does the LORD hate: yes, seven are an abomination (disgusting) to Him. A proud look, a lying tongue, and hands that shed innocent blood. A heart that devises wicked imaginations, feet that are swift in running to mischief, a false witness that speaks lies, and he that sows discord among brethren.” Prov 6:16-19
“I have loved you (Israel), saith the LORD, Yet you say, 'Wherein have You loved us?' Wasn’t Esau Jacob’s brother? Yet I loved Jacob and I hated Esau…” Malachi 1:2-3
