This verse tells us that the Lord was pleased to make Israel—and by extension, us—His own. What does that mean for us?
It means that He chose us not because we’re special by our own merit, but because He wanted to. Because it gives Him pleasure to love us so lavishly, to redeem us from sin and make us His beloved children.
And because we are now and forever His, He will always be for us—He won’t let us go down the wrong path without coming to our rescue. He will keep disciplining us for our good.
