This is from the blessing God commanded Aaron to pronounce upon the people of Israel (Numbers 6:24-26). God wants to bless his people. He shines his face upon us.
Sadly, most of us miss it most of the time. The psalmist speaks of "seeking God's face" (Psalm 27:8). He acknowledges that he needs to tune in to the gaze of God.
If God is looking at me, then I can look at him in return.
Sometimes eye contact, in human interactions, can be embarrassing or awkward. To look deeply into someone's eyes allows you to get a glimpse into his or her soul. Most often we look away from a person who stares at us. We don't want to be known.
When lovers look into each other's eyes, it brings such a deep connection of knowing. It is a profound expression of love. It fuses vulnerability with joy.
Making eye contact with God is more difficult than I imagined. When I try to return his loving gaze, I am easily distracted. I turn my spirit's gaze away from him. I'm not sure why. Only with effort can I keep my gaze on him, and thereby receive the warmth of his face shining on me.
The radiance of his eyes soothes me, calms me, reassures me, transforms me. I receive his love. He makes me new. He makes me more like himself.
