I think that most of us do not think that this is what God requires of us this day and age – this is more like OT stuff and not NT. However, the character of God does not change – He is the same, always.
At least we start off the perception that walking in the law is not healthy – so we need to ask the difference between that and the law of God – is there a difference?
First of all the law of God is perfect. Those that keep His testimonies and seek Him with their whole heart, keeping away from those things that keep them from God and turning to those things that bring them closer to Him are blessed.
God has obviously given the commandments and laws so that we can diligently observe them, for His ways are established – why would I not observe them? I will not be shamed when I have respect for His commandments. In fact, I will give thanks when I hear testimonies of how right it is to follow God for those testimonies have a common element – God does not forsake those who follow Him.
