Jesus gave many parables to help us understand the ways of God, and among the most powerful is the parable of the mustard seed. Though short in words, it carries a deep truth about the kingdom of heaven, the work of the Spirit, and the new covenant God promised through the prophets.
Jesus said:
“The kingdom of heaven is like a mustard seed, which a man took and sowed in his field, which indeed is the least of all the seeds; but when it is grown it is greater than the herbs and becomes a tree, so that the birds of the air come and nest in its branches.” (Matthew 13:31–32, NKJV)
The mustard seed is tiny—easily overlooked—yet it holds within it the power to grow into something great. In the same way, the work of God in the heart begins small. When someone first hears His Word and turns toward Him, it may seem like a small beginning. But this is how the new covenant works. As God said through Jeremiah, “I will put My law in their minds, and write it on their hearts.” The seed is planted by God, but it grows as the heart agrees to the covenant and opens to His Spirit.
Just like any true covenant, both sides must be faithful. God is always ready—He sows the seed, He sends His Spirit, He offers forgiveness and grace. But we must receive that seed, believe His Word, and allow the Spirit to change us from within. That is how the kingdom of heaven grows—not first on the outside, but within the heart of the believer.
The seed then begins to grow. Slowly, quietly, but steadily, it takes root. The law that once felt like a list of commands now becomes a source of joy and love. The Sabbath becomes rest with God, not a burden. Honoring others, speaking truth, and keeping pure no longer feel like rules but become natural, like the fruit a tree bears when it is healthy. This is the life that comes when God’s law is written in the heart—not cold obedience, but joyful righteousness.
As the seed grows, it becomes a tree. This shows that the work of God, when it is full, becomes a blessing not only to the one who receives it but also to others. Jesus said the birds come and rest in its branches. A person who walks with God, in whom the Spirit lives and the law is written, becomes like that tree—strong, rooted, and a shelter for others. Their life reflects peace, kindness, humility, and strength. They become a witness of the living God.
Isaiah spoke of this long before when he said, “They shall be called trees of righteousness, the planting of the Lord, that He may be glorified.” God is not just growing individuals—He is preparing a people who truly reflect His kingdom on earth. Though it starts small, even hidden, His work will become a mighty tree. And those who accept the covenant, those who let the Spirit write the law in their hearts, will be part of that tree.
The mustard seed teaches us that what begins small can become something powerful and full of life. It shows us how God’s kingdom grows inside those who are willing. It reminds us that obedience, love, and righteousness may begin as a seed—but by the Spirit, they will grow strong. The covenant of God is alive, and those who receive it will never remain the same.
