“I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery.” (Deuteronomy 5:6 ESV)
The Ten Commandments start by reminding the people of what God had done on their behalf. This is the LORD God (that is Yahweh Elohim – the personal, covenant keeping and yet all powerful God). The Ten Commandments are built upon what God had done for the people; their obedience was a response in gratitude for what God had graciously done for them – not as a means to earn approval and salvation.
The Israelites are constantly being called to remember the events of the past, particularly how faithful God had been to them. That is not because they normally had cognitively forgotten what God had done, that is because it was not longer impacting their hearts. When we are no longer touched by the magnificent grandeur of God and all that He has done on our behalf our faith begins to wither into drudgery and duty. Because we are prone to forget, we must be disciplined to remember the majesty of God by praying for Him to reveal Himself to us and by searching the scriptures for God’s sovereignty, grace and holiness.
