“All the people answered as one, ‘Everything Adonai has said, we will do..” (Ex. 19:8, CJB)
“Moshe stood at the entrance to the camp and shouted, ‘Whoever is for Adonai, come to me.'” (Ex. 32:26, CJB) “Moshe said, ‘You have consecrated yourselves to Adonai, because everyone of you has been against his own son, and against his own kinsman, in order to bring a blessing on yourselves today.'” (Ex. 32:29, CJB)
Although the Hebrew people had vowed to do everything God commanded them to do, a short time later, they built an idol and plunged into idolatry and revelry. Words are cheap. Many claim to follow God. Few really follow through. It means more than just a mental assent to what He says.
Moses demanded a separation for those who were really serious about obeying God. Moses was the symbol and conduit of God’s teachings and instructions, or Torah. So those who wanted to escape God’s judgment had to align themselves with Moses, even at the cost of leaving behind their own loved ones who refused to embrace His laws. There is a parallel verse in the NT.
“He who loves father or mother more than Me is not worthy of Me; and he who loves son or daughter more than Me is not worthy of Me.” (Matt. 10:37, NAS)
If we fit in with the majority, there’s a chance we may not be really concecrated to God.
