" The first commandment is not only a command, but a promise. In other words, one can even find the gospel in the commandment. Essentially, God is telling His people, “Look, I am the sovereign God of history who spoke this world into existence and led you out of slavery. I am the only one in this mess who can save you because I am all-powerful. But not only am I the only one who can save you, I want to save you, because I am gracious and merciful, in spite of the fact that you do not deserve it. Because I am sovereign, I am the only one who can save you; because I alone can unconditionally love, I am the only one who wants to save you and will continue to save you in spite of your sin and resistance. "
