Philippians 2 and Christ’s own question about David’s son in Matthew 22 both press the same title, Son of God, further than casual religious language usually allows. In the Old Testament, a son is an heir, and the inheritance in view here is nothing less than God himself. Christ’s perfect sonship is what makes believers sons and heirs alongside him, not merely beneficiaries of his.
Continuing from God’s sovereignty over time, the focus turns to how we ourselves are meant to use it. Adam is more than a mere creature; he is a son, and the garden he is given anticipates, with real similarities and differences, the paradise of Revelation 22.
