“Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might.”
??Deuteronomy? ?6:4-5? ?ESV??
The Gospel is at the very essence, love. Our response to the Gospel and Gods challenge and commandment to us lies in the essence of who he is (love).
The command found here is the central command as every other commandment we are given flows out of this commandment. We cannot love others if we do not love God.
