Treasury of Scripture Knowledge
And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:
The expert in the law said to him, "That is true, Teacher; you are right to say that he is one, and there is no one else besides him.
Listen, Israel: The Lord is our God, the Lord is one!
Now, Israel, what does the Lord your God require of you except to revere him, to obey all his commandments, to love him, to serve him with all your mind and being,
The Lord your God will also cleanse your heart and the hearts of your descendants so that you may love him with all your mind and being and so that you may live.
Give me your heart, my son, and let your eyes observe my ways;
"Whoever loves father or mother more than me is not worthy of me, and whoever loves son or daughter more than me is not worthy of me.
The expert answered, "Love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind, and love your neighbor as yourself."
1 Timothy 1:5
But the aim of our instruction is love that comes from a pure heart, a good conscience, and a sincere faith.
"Teacher, which commandment in the law is the greatest?"
You believe that God is one; well and good. Even the demons believe that -- and tremble with fear.
1 John 4:21
And the commandment we have from him is this: that the one who loves God should love his fellow Christian too.
