God is love, and the Scriptures contain no equivalent statements with respect to other qualities of the divine nature. Love is the highest characteristic of God and the one attribute in which all others harmoniously blend.
The love of God and Christ is greater than mere kindness or benevolence. The love of Christ underpins everything He has done and is doing, even though many facts exist that we cannot fully understand due to our limited knowledge.
Love is keeping the commandments. Love is submitting to God. God has other qualities; but He is primarily known by this one. He wants His children to be known by this too. So, as we obey His commands, we are showing love toward God and love toward neighbor.
I think that is very clear. Our keeping of the commandments (which is love) is our response to God's love—first to Him, and then out to our fellow man.
