Living in the light of the Lord’s countenance is just another way of saying that we live close enough to see His face—and conversely that He sees us. The idea is captured really well in Aaron’s blessing of the sons of Israel in Numbers 6:24-26: “The Lord bless you, and keep you; the Lord make His face shine on you, and be gracious to you; the Lord lift up His countenance on you, and give you peace.” The idea of living in light of the Lord’s countenance carries with it His blessing. It also carries with it a sense of accountability. It’s basically like living in His throne room—and that’s where the accountability comes in. We’re called to live differently in the throne room so that when His face shines upon us in holiness we’re not ashamed.
