Believe it or not, the title’s question above has an incredibly simple answer, but the things you must understand to grasp it are not so easy. Let us start with another question.
“These six things the Lord hates, yes, seven are an abomination to Him [Lit. to His soul]: a proud look, a lying tongue, hands that shed innocent blood, a heart that devises wicked plans, feet that are swift in running to evil, a false witness who speaks lies [even under oath], and one who sows discord among brethren.” Proverbs 6:16-19.
