Pr 6:16 | These six things the LORD hates, Yes, seven are an abomination to Him:
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, And one who sows discord among brethren.
The things which the Lord hates are all in disobedience to His ten commandments.
Deu. 6:4-5 | "Hear, O Israel: The LORD our God, the LORD is one! You shall love the LORD your God with all your heart, with all your soul, and with all your strength."
2 John 1:6 | This is love, that we walk according to His commandments. This is the commandment, that as you have heard from the beginning, you should walk in it.
The Lord hates the breaking of His commands, we are not to break them but to love God, therefore we are to love God by keeping His commands.
(NKJV) "We know that we have passed from death to life because we love the brethren. Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him."
Notice that it is not merely "others" we love, but the Christian brethren. They will know we are christians by our self sacrifice and unity in the church. A strong church family is more attractive to unbelievers than a broken evangelistic one.
Yet even if we love to the fullest:
1 John 3:13 | Do not marvel, my brethren, if the world hates you.
John 15:19 | "If you were of the world, the world would love its own. Yet because you are not of the world, but I chose you out of the world, therefore the world hates you.
