In His glorious covenant with Abraham, the Lord promised that He would make Abraham a blessing to many nations (Genesis 12) and also that Abraham would: a) have an heir, b) his descendants would be as numerous as the stars, and c) they would inherit the land of Canaan (Genesis 15). Today in hindsight and with the progressive nature of revelation, we can see how all of these promises have come to pass, but the fulfillment was not as evident at the time Moses wrote Exodus. Abraham had an heir and his descendants were many, but they were bound in slavery in Egypt. The Lord miraculously set them free from their bondage and is bringing them into the Promised Land. On this journey they are called to the very mountain on which the Lord spoke to Moses in chapter 3. In what is truly an epic event within Exodus and all of the Old Testament, the Lord will again speak; this time not only to Moses, but to all the people of Israel. In our text and the verses that follow, God gives what is known as the Mosaic Law. It is a covenant that God made with Israel.
We’ll open up our text with first looking at the giver of the Law who is none other than Yahweh! Then in verses 3-17 we will see how the Law reveals certain attributes of the Lord Himself! Finally we will find Israel’s reply after receiving the law. Israel already answered Moses and said, “All that the Lord commands we will do” (Exodus 19:8) and will affirm this again in Exodus 24:3. But of course, they could not keep their word.
Why could Israel not do as they said they would? Was there a problem with the Law? No; it was with the people’s heart. They needed the Law written afresh on their hearts (Deuteronomy 30:6-8). They needed to be born again! Their failure to keep the Law points the Israelites to their sinful hearts and their need to repent and trust in the Lord. The Law also points to the sinless One who would come and fulfill the Law completely. So, the Law points forward to Jesus Christ! (See Matthew 5:17; Hebrews 4:15; and 1 John 3:5). We will close the message looking at the many tests in the New Testament about the Law and its function in the life of the believer in Christ.
