God’s commands reveal his character and how we fulfil it, reveals ours.
This may not be theologically sound, but how I imagine it to be, and one alternative take of when God said in Matthew 5:28 “but I say, anyone who even looks at a woman with last in his eye has already committee adultery in his heart.” Here, the command was to not commit adultery, but the manner in which we fulfil it reveals our sinful nature. Therefore, it is important to pay attention to the inner workings of God’s commands. When commanded to honour thy father and mother, while I may not speak ill of them to others or disobey, how I go about it is just as important. Of course to pay attention to that the command has to be first followed and there is some good in that but it is not enough. This reminds me of how Jews follow many old testament laws; laws that tend to be outward and it’s adherence measurable. While some of these are still relevant, the meaning behind these commands and understanding them above simply following them is equally if not more important. Which is probably also why NT commands focus a lot more on the ‘inside’ things not immediately apparent and without a tangible measurement.
By paying attention to how we carry out the commands of God, we begin to engage our entire being in this process of following Jesus. Fun fact, we also edge closer to fulfilling the greatest command: to love the Lord your God with all your heart and with all your soul and with all your mind(ref. Matt 22:37).
