What follows can be surprising.
"May God be gracious to us and bless us and make his face to shine upon us, that..."
Now certainly, we know God's blessing can be immediate and tangible in our daily lives. We know that his blessing isn't always apparent. We know that his blessing isn't necessarily what we had in mind. We know that his blessing can overwhelm us with joy and gladness, sometimes tears. We know that his blessing is often pervasive and greater than our imagination. So often we know his blessing extends beyond our own thinking, however, in our own regular, finite thinking, we assume his blessing falls chiefly and primarily on us and goes no further. Is it healthy for a creature to be the end-all recipient of the Creator's eternal blessing? I don't think we can handle the weight of such a gracious gift.
Do we know that his blessing, his gracious act towards us and his causing his face to shine upon us is ultimately for himself? The very notion that he would involve us in his blessing is wonderful, but it doesn't come near the wonder of his self-revelation in Jesus. His blessing is that we may know the supremacy of Christ and so glorify his name! What participation he has given us in his saving purpose and eternal plan!
