Jesus and the mustard seed

Jesus told them another parable: The kingdom of heaven is like a mustard seed, which a man took and planted in his field. Though it is the smallest of all seeds, yet when it grows, it is the largest of garden plants and becomes a tree, so that the birds come and perch in its branches.

Matthew 13:31-32

Imagine catching up with old friends or family members you haven’t seen for some time. They have young children, and you hear yourself stating that most obvious of comments, “Gosh, haven’t they grown!” Your friends could respond, rolling their eyes, “Well, what do you expect? Isn’t that exactly what healthy children do? Why the surprise?” But of course they don’t: no, they smile sweetly and take it as a compliment.

Growth is a wonderful thing. It happens both in us and around us every minute of very day. But we take it so much for granted that we barely notice it until our attention is drawn to it; we certainly don’t notice it actually happening.

Jesus came to his people Israel announcing the coming of the kingdom of God. God, he said, was fulfilling the promises made in bygone centuries to his people – promises declaring a new start, a whole new way of being God’s people, and a new king, the Messiah, who he would claim to be. And he provided vivid, down-to-earth illustrations to make this real for his hearers.

One truth about the new kingdom is that it would grow. I personally haven’t the remotest idea what a mustard seed looks like, but Jesus obviously assumed his hearers would, and that it was extremely tiny. So, he says, see how it grows! – big enough to become a tree, and a big enough tree to provide a home for the birds! What a transformation!

As Christians we hear a lot about “church growth”, by which we usually mean an increase in the numbers of people who identify with some branch of the world-wide church. And that is certainly a part of the picture Jesus is drawing. I don’t know what the latest statistics say, but certainly the first followers of Jesus – that not particularly impressive bunch of twelve Galileans – would have been staggered to fore-see what we see today, in 2026. But the story of growth is by no means simple, and parables like the mustard seed encourage us to use our imaginations to draw out various implications…

One very obvious implication is the matter of time.

Mustard seeds don’t mature into full-grown plants in five minutes. I don’t know how long it takes, but this is one of the miracles of growth: it’s happening all the time, yet much of it we simply don’t see. There are trees in Sherwood Forest which go back literally centuries.

The implication for the kingdom of God? That God’s time-scale is very different from ours; and that therefore we must learn the gift of patience. “Why doesn’t God do something?” we ask in frustration, especially over an issue that is especially acute. That’s understandable. But what only the eye of faith can see is that he is doing something; he is, if I might put it so, “on the case”, and things, hidden things, are happening we know nothing about.

One particular application of this - not explicitly spelled out in the Bible, but surely correct – is the practice of persevering prayer. Jesus encourages his people not just to pray, but to go on praying. The classic text for this is Matthew 7:7-8: “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you…” where (so the scholars tell us) the Greek tense implies a continuous asking, seeking and knocking, not just a one-off request.

I have adopted the habit of praying from lists – not only, of course, but lists that have built up over many years form a large bulk of my daily prayers. You may prefer to pray more spontaneously, and that’s fine, but for me it helps to maintain a discipline which enables me to keep focussed.

Does it sometimes become rather mechanical, even routine? Yes, it does – especially when, having prayed for some situation or some person for what seems like the thousandth time (what may in fact be the thousandth time!) and aware that no tangible sign of change has happened, one can feel discouraged. But just as that mustard seed is changing in the depths of the soil, may not my renewed prayer be slowly germinating in the purposes of God?

Yes, there are times to cull such a list, for whatever reason – and God will make that time clear. But patient perseverance, pursued in faith – why would God neglect such a practice? Christian, see every prayer not only as a strengthening of your relationship with God, but as a seed sown!

Your church is not flourishing as you long to see? Don’t give up, but join with your fellow members in determined prayer. That person in need of healing seems to get no better? Don’t give up, but pray even harder. And as we look around us at our troubled world, things just seem to get worse? Remember, Jesus taught us to pray as a matter of course that God’s will would be done “on earth as in heaven”, so let’s take him up on that. If we don’t model ourselves on “the Lord’s prayer” (Matthew 6: 9-13), how can we claim to be his disciples? God forgive us when we limit our prayers to our own little local bubble. Yes, every time we pray , in however repetitive a manner, something happens, even though we may never see it in this earthly life. Remember, every prayer is a seed…

Father, thank you that there is never a moment when you are not at work in this world that you made and that you love. And thank you that my feeble prayers, even when they seem dull and repetitive, play their part in your work. Give me grace to persevere and faith to believe that I will one day see the completion of your purposes. Amen.
