“As for me, I shall behold your face in righteousness; when I awake, I shall be satisfied with your likeness.” -Psalm 17:15
The tenor of verse 15 is communal rather than strictly judicial. David’s considers his own state of being in contrast to what the wicked can expect from God.
The wicked are earthly and material. They will be confronted and subdued by the hand and sword of God. But as for David, his existence is eternal and transcends the limits of earthly desires. He rises to the heavens as it were and sees the face of God in righteousness and is satisfied (lit., has more than enough) to see God’s likeness as a son does his own father.
This contrast between the goals and satisfactions of the two groups of men highlight the hope, peace, and joy of every Christian similar to the way Paul describes in his letter to the Philippians.
“For many, of whom I have often told you and now tell you even with tears, walk as enemies of the cross of Christ. Their end is destruction, their god is their belly, and they glory in their shame, with minds set on earthly things. But our citizenship is in heaven, and from it we await a Savior, the Lord Jesus Christ, who will transform our lowly body to be like his glorious body, by the power that enables him even to subject all things to himself.” -Philippians 3:18–21
