Who can be God's friend? Who can come into his presence and enjoy table-fellowship with him? Psalm 15 has been referred to as a "liturgy of entrance." As pilgrims came to worship in Jerusalem, before they entered the place of worship, they asked a question: "Who can come in?" The answer is, "Only those who mirror the character of the one they've come to worship."

As we will see, verse one asks who can "sojourn" or "camp" with God, but by the end of the Psalm we're told that those who mirror their God will not be temporary aliens in his house, but children who are welcomed to an eternal and unshakeable home.
