Who? Jesus, that’s who.
The opening questions of this psalm ask, “Who?” and if we think that the answer to either of them is “me,” we are only partially correct.
Read on. “Walks blamelessly.” “Does what is right.” “Speaks truth in his heart.” Speaking truthfully, neither you nor I walk blamelessly but seek to avoid blame for the way we walk. You and I do what is right in our own eyes, but that is not what others see when they look at our actions, not to mention what we do when we think nobody is looking. The truth we speak contains fibs and white lies or at the very least our own interpretation of things in an attempt to make ourselves look good. It is impossible to get through the second verse and honestly see ourselves depicted.
But we are. We are because Jesus is. Jesus is described in these verses as the one who has the right to sojourn in the Lord Yahweh’s tent and to dwell on God’s holy hill. He is holy because he walks blamelessly. Jesus does what is right. Jesus speaks truth in his heart. Jesus does not slander. Jesus does no evil against his neighbor. Jesus does… and he does it for you. For me.
He does these things for our sake. He fulfills the requirements of God’s holy law as they are laid out in this Psalm and delivers them to us by suffering in our place for our transgression of that law. He qualifies us to be sojourners in God’s house through our baptism into him and invites us to feast on his body and blood that was given up on the holy hill of crucifixion.
Who? Jesus… and you, and me bought into the dwelling place of God because Jesus did what the Father willed.
