Showing our failings or falling short of God's glory is precisely what all the commandments are about. They are good but we deliberately and willfully don't keep them. Like all the other commandments, our Lord gave the example of the Good Samaritan to show our failings. Our Lord concludes, "Go and do likewise and you shall live." This is a very sly and pointed remark to us to show us that we will not go and do likewise. Sure we might try to do something nice for someone once in a while, but it's a standard we cannot keep up. And if we break one of the laws we break it all.
While admittedly it helps us to think of doing good things, it really is pride and arrogance on our part to think that we do any good works. All good things come from the Father who works through us. God gives us our good works. We understand that we do nothing good apart from the Father and the Son. Only when we abide in Christ, does Christ work through us by means of the Holy Spirit to create our good works.
We don't follow the commandments because it is a "rule". We follow the commandments because God has put it on our heart. And if it wasn't for the Holy Spirit and God writing this upon our hearts, none of us would do anything pleasing to God. It is folly to think otherwise. We don't reciprocate the love of God because that implies our work and strength. We imitate the love because of Christ because of the Holy Spirit working through us. And God has already created our good works to the praise of His glory.
