When Jesus was asked about the greatest commandments, He responded with these words:
"You shall love the Lord your God with all your heart and with all your soul and with all your mind. This is the great and first commandment. And the second is like it: You shall love your neighbor as yourself. On these two commandments depend all the Law and the Prophets"
Matthew 22:37-40 (Esv).
This was a brilliant response. He was showing us that these two commands are the cornerstone upon which all the other commands of God are created. In other words, you could say that any command that the Lord has given in the Bible is an application of one of these two commands. They all have to do with loving God and loving our neighbor.
“By this all people will know that you are my disciples, if you have love for one another” (John 13:35). “We love because He first loved us” (1 John 4:19). Obedience to God is an overflow of our love for Him, which itself is an outworking of joy that swells up in us when we consider His love expressed to us in Christ. Therefore, as we meditate on the Gospel we see God's love for us and this produces in us the love and worship needed to follow Jesus faithfully.
