The very beginning of verse 11 suggests a two-way relationship between us and the sacred text. Paul, who repeatedly uses quotations from Scripture to confirm his words, here on the contrary himself affirms that a certain saying is true. This mutual recognition of the presence of the Holy Spirit in the Word and in a person is remarkable.
What follows is apparently a fragment of an ancient Christian hymn, whose main meaning is the proclamation that life in union with God, beginning here with suffering and death shared with Jesus Christ, continues after death in His Resurrection and reign. Let us note the somewhat paradoxical ending of this fragment: our denial of God, that is, a break in relationship with Him, means our unfaithfulness, but God's denial of us is not unfaithfulness, because He remains faithful to Himself and to His purpose, which gives hope to our existence in this changeable and faithless world.
