A study of Scripture will reveal that we need the face of God for blessing, for shalom, for life to flourish; and when God turns his face away things fall into disarray. Of course there is the problem of the fact that no human being can see the face of God as it really is, and live. We have that problem ultimately solved in God becoming human, in the person of God's Son, Jesus. We read:
For God, who said, "Let light shine out of darkness," made his light shine in our hearts to give us the light of the knowledge of God's glory displayed in the face of Christ.For me, the hidden face of God is part of my life and experience (I don't like to use the word "experience", because I think we've practically come to idolize experience. Though experience in its proper place is important and indispensable.) and understood rightly according to the revelation of God in Scripture and in Jesus, is a marked improvement over so much popular theology.
Psalmists (see here for uses of "face" in the psalms; very good and helpful) repeatedly speak of seeking the face of God. This is certainly ongoing for us; we need to do the same.
We also have seen that in Jesus we see the face of God. This makes for us the revelation of Jesus central in our effort to see the face of God. Jesus is at the center; we never are. But by faith we fit into this wonderful ongoing story of God.
