St Cyril of Jerusalem, using the simplest of metaphors, helps us understand the Christ in a very accessible way:
But why did Christ call the grace of the Spirit water?...Water comes down from heaven as rain, and although it is always the same in itself, it produces many different effects, one in the palm tree, another in the vine, and so on throughout the whole of creation. It does not come down, now as one thing, now as another, but while remaining essentially the same, it adapts itself to the needs of every creature that receives it.That Jesus' Spirit is like rain invites us to sit by a window, watch the rain come down and imagine it nurturing and nourishing every plant and tree we can see. When it penetrates the roots of an oak tree, it allows the oak to be itself, strong and majestic, but when it drenches the roots of a tomato plant, it makes it possible for the plant to produce tomatoes. The miracle of grace and growth is obvious and important.
Our lives, lived in faith, should be like rain in others' lives. It is not our task to change those around us, but to help them become themselves in faith. When we give of ourselves freely to those in need, they can become the person God intends and needs them to become for the sake of God's reign. As God sends Jesus, and Jesus send us, so must we send others in Jesus' name to be signs of God's love.
Today, pray that those closest to you will become God's face in the world.
Who has been like rain in your faith life?
