Today’s devotion comes from Exodus 34:18-28.
“18 “You shall observe the Feast of Unleavened Bread. For seven days you are to eat unleavened bread, as I commanded you, at the appointed time in the month of Abib, for in the month of Abib you came out of Egypt.
19 “The first offspring from every womb belongs to Me, and all your male livestock, the first offspring from cattle and sheep. 20 You shall redeem with a lamb the first offspring from a donkey; and if you do not redeem it, then you shall break its neck. You shall redeem all the firstborn of your sons. None shall appear before Me empty-handed.
21 “You shall work six days, but on the seventh day you shall rest; even during plowing time and harvest you shall rest. 22 You shall celebrate the Feast of Weeks, that is, the first fruits of the wheat harvest, and the Feast of Ingathering at the turn of the year. 23 Three times a year all your males are to appear before the Lord God, the God of Israel. 24 For I will drive out nations before you and enlarge your borders, and no man shall covet your land when you go up three times a year to appear before the Lord your God.
25 “You shall not offer the blood of My sacrifice with leavened bread, nor is the sacrifice of the Feast of the Passover to be left over until morning.
26 “You shall bring the very first of the first fruits of your soil into the house of the Lord your God.
“You shall not boil a young goat in its mother’s milk.”
27 Then the Lord said to Moses, “Write down these words, for in accordance with these words I have made a covenant with you and with Israel.” 28 So he was there with the Lord forty days and forty nights; he did not eat bread or drink water. And he wrote on the tablets the words of the covenant, the Ten Commandments.” Exodus 34:18-28.
—————-
These commands (and yesterday’s Scripture summarized by the second commandment) were clearly separate and added to the promises of the covenant made earlier in the chapter, almost as if they were a non-sequitor to the promises of God in verse 10: ” Then God said, “Behold, I am going to make a covenant. Before all your people I will perform miracles which have not been produced in all the earth nor among any of the nations; and all the people among whom you live will see the working of the Lord, for it is a fearful thing that I am going to perform with you.” Exodus 34:10.
The importance of the distinction between promises and commands is that God’s promises are not going to be invalidated by man’s inability to obey the commands.
“15 Brethren, I speak in terms of human relations: even though it is only a man’s covenant, yet when it has been ratified, no one sets it aside or adds conditions to it. 16 Now the promises were spoken to Abraham and to his seed. He does not say, “And to seeds,” as referring to many, but rather to one, “And to your seed,” that is, Christ. 17 What I am saying is this: the Law, which came four hundred and thirty years later, does not invalidate a covenant previously ratified by God, so as to nullify the promise. 18 For if the inheritance is based on law, it is no longer based on a promise; but God has granted it to Abraham by means of a promise.
19 Why the Law then? It was added because of transgressions, having been ordained through angels by the agency of a mediator, until the seed would come to whom the promise had been made. 20 Now a mediator is not for one party only; whereas God is only one. 21 Is the Law then contrary to the promises of God? May it never be! For if a law had been given which was able to impart life, then righteousness would indeed have been based on law. 22 But the Scripture has shut up everyone under sin, so that the promise by faith in Jesus Christ might be given to those who believe.
23 But before faith came, we were kept in custody under the law, being shut up to the faith which was later to be revealed. 24 Therefore the Law has become our tutor to lead us to Christ, so that we may be justified by faith. 25 But now that faith has come, we are no longer under a tutor. 26 For you are all sons of God through faith in Christ Jesus. 27 For all of you who were baptized into Christ have clothed yourselves with Christ. 28 There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus. 29 And if you belong to Christ, then you are Abraham’s descendants, heirs according to promise.” Galatians 3:15-29.
