If God were only one person, he could be a lover, but not love itself. The Father loves the Son and the Son loves the Father, and the Spirit is the love proceeding from both, from all eternity. If that were not so, then God would need us, would be incomplete without us, without someone to love. Then his creating us would not be wholly unselfish, but selfish, from his own need. Love is a flower, and hope is its stem.
Salvation is the whole plant.
God's grace, God's own life, comes into us by faith, like water through a tree's roots. It rises in us by hope, like sap through the trunk. And it flowers from our branches, fruit for our neighbor's use. Faith is like an anchor. Faith must be faithful.
