Romans 8:1-27 is its own commentary
It speaks cosmologically of the restoration of all creation and how the followers of Christ are called to emulate him in, as N.T. Wright says, standing “between the pain of the world and the love of God,” not as a wall or barrier, but the span of a bridge, or a linking arm.
This ultimately is what the cross of Christ stands for. It is transformed from a shameful and cruel instrument of execution to a symbol of transforming love.
