Read Deuteronomy 30 and Isaiah 57.
This devotional is about Deuteronomy 30:6.
It is easy to read the Old Testament and come to some false conclusions. Two false conclusions that come to mind are (1) that Israel had the capability to keep the law of God and that (2) God would be pleased with them if they kept his law.
False conclusion number 2 would be true but it is impossible because of conclusion number 1. Israel had no chance of enjoying all the benefits God promised in his covenant because Israel was a nation made up of sinners. Their obedience to his Word, therefore, would only ever be partial and half-hearted. Because God is perfect and demands perfection, the sins of the people–no matter how minor they seem to us–would always render them guilty before their holy God. We can see from Israel’s history that God did bless them when, in a general sense as a nation, they kept his commands not to worship idols or commit murder, or oppress the poor. But each individual person would be guilty of things like coveting his/her neighbor’s stuff.
So all of these laws in the Old Testament were designed to show God’s people and anyone else who was paying attention that God is holy and therefore, people are always guilty before him. God used the law to teach this so that people would come before him genuinely seeking his forgiveness and his help to be obedient to his word.
Verse 6 here in Deuteronomy 30 describes the spiritual work that needed to happen for people to truly worship and follow him. That verse says, “The Lord your God will circumcise your hearts and the hearts of your descendants, so that you may love him with all your heart and with all your soul, and live.” Circumcision, of course, was the covenant mark of the Abrahamic covenant. Each boy who was circumcised was, by that act, showing that they belonged God’s people, the descendants of Abraham. When verse 6 says that “God will circumcise your hearts” Moses is describing the spiritual act of belonging to God, being marked as a genuine believer of God. This is what we would call in the New Testament “regeneration,” the work of the Holy Spirit that makes someone a child of God.
There are important differences between Israel and the church but it is important to understand that God’s people have always needed his grace through faith and the regenerating work of the Spirit in order to be his people from the heart, not just in name only. What I’m saying is that God’s people–Old or New Testament–have always needed God to save them, to act on our behalf and make us his by the work of the Spirit. Believers in every age have all been saved by the grace of God and never by religious rituals or meritorious good works.
Are you trusting in your religious rituals or are you trusting in the grace of God alone for your salvation?
