“Be mine!” may be a message on a valentine card. But what does it mean to be God’s treasured possession? How can you be God’s people? This reflection focuses on God making his covenant with Israel at Mt. Sinai–and his covenant with you in Christ.
“Genesis 3:15 already contains the entire covenant in a nutshell and all the benefits of grace. God breaks the first covenant made by the first humans with Satan, puts enmity between them, brings the first humans over to his side, and promises them victory over the power of the enemy. The one great promise to Abraham is ‘I will be your God, and you and your descendants will be my people’ (Gen. 17:8 paraphrase). And this is the principle content of God’s covenant with Israel as well. God is Israel’s God, and Israel is his people (Exod. 19:6; 29:46; etc.). Israel, accordingly, receives a wide assortment of blessings, not only temporal blessings, such as the land of Canaan, fruitfulness in marriage, a long life, prosperity, plus victory over its enemies, but also spiritual and eternal blessings, such as God’s dwelling among them (Exod. 29:45; Lev. 24:12), the forgiveness of sins (Exod. 20:6; 34:7; Num. 14:18; Deut 4:31; Pss. 32; 103; etc.), sonship. . . sanctification. . . and so on.” (Herman Bavinck, Reformed Dogmatics, Vol. 3, p. 221).
