Luke 13:18–19 (NKJV)
18 Then He said, “What is the kingdom of God like? And to what shall I compare it? 19 It is like a mustard seed, which a man took and put in his garden; and it grew and became a large tree, and the birds of the air nested in its branches.”
As I have emphasized the last couple years at this time, we are often tempted to muddle our Christianity with our Americanness. This temptation to mistake our cultural mileau for Christian piety is not unique to us, but the particular ways in which our culture influences us are unique. One way our Americanness affects our conception of Christianity is our love affair with that which is spontaneous or new or different. We tend to grow tired of, what we call, the “same old thing” and have a hankering for some new fad to bring life back into our Christian walk.
But what Jesus articulates for us in his parables of the kingdom is that the way the Holy Spirit works both in our individual lives and in the life of His Church is better pictured by the growth of a tree than the lighting of a sparkler. Sparklers, of course, are fun and exciting – they burn bright and shed their fire on all around them. But sparklers soon burn out while trees, planted and taking root, slowly grow over time; growing almost imperceptibly, soaking up the nutrients in the soil and increasingly displaying the glory of their Creator.
This steady, slow, natural growth is the way Christ typically works in the lives of His disciples. Normal Christian growth involves long periods of steady plodding – plodding that brings prosperity but plodding nonetheless. Steady plodding. Few sprints; mainly marathons. A long obedience in the same direction.
You may not know, but the last five months in the Church Year are called “ordinary time.” It is a time of year when there are no special feasts and celebrations; just the regular time of the Spirit’s work in the Church. After the pouring out of the Spirit at Pentecost, the Spirit began working in the Church, gradually transforming the people of God into the image of Christ. Hence the color of this period is green, a color of growth. Tree-like growth.
So one thing that you probably noticed, if you’ve been at Trinity Church a while, is that for these last five months we have used the same greeting, the same words of confession, and the same version of the Creed. For five months. Why have we done this? There’s no biblical requirement that we do so. We could have changed them weekly, monthly, or periodically – and we have in the past. God has left such decisions to the wisdom of church officers. So why have we kept them the same the last couple years? To highlight that the course of our Christian lives is only occasionally interrupted by unusual acts and works of God. More typically God works in our lives through steady plodding, slow growth, gradual transformation – through what theologians have called the ordinary means of grace: the preaching of the Word and the administration of the sacraments of baptism and the Lord’s Supper.
In a couple weeks we’ll be introducing some changes: entering a new church year when Advent arrives and we’ll have a different Call to Worship, a different Confession, a different Creed. Before we change, I wanted to draw to your attention the fact that for these last five months we haven’t changed. Perhaps you noticed; perhaps you’ve wondered if this is ever going to change. And perhaps you’ve thought the same thing about periods in your own life and spiritual development. And the message of Jesus is that He is at work growing His kingdom and even growing you – so trust Him and keep plodding.
Reminded that Jesus’ work in our lives is often gradual, like the growth of a tree, we are alerted that often our hankering for something spontaneous or new or different is not an impulse of our Christian faith but our Americanness. And this reminds us that we need to confess our fickleness to the Lord and ask Him to enable us to practice a long obedience in the same direction. So let us kneel as we confess our sins together.
