His grace in kindness is “toward us.” You could translate this “to us” or even “over us” or “on us.” This is personal. Not abstract. His heart, his thoughts, now and on into eternity, are toward us. His grace is not a blob out there that we have to figure out how to get into. He sends his grace to us, personally, individually, eternally. Indeed, he sends himself—there’s no such “thing” as grace (remembering that such a view is Roman Catholic teaching). He sends not grace in the abstract but Christ himself. That’s why Paul immediately adds “in Christ Jesus.”
