Why is it important to not despise small beginnings in ministry?

In the parables of the mustard seed and leaven, we learn the valuable lesson of not despising small beginnings. The mustard seed, though tiny, grows into a great tree that offers shelter to birds, symbolizing how seemingly insignificant acts of faith can lead to substantial outcomes in God's kingdom. Similarly, the leaven, though hidden, enriches the whole batch of dough. This illustrates that God uses small and humble means to accomplish His grand purposes. The growth of the church and the effects of the gospel may often be unseen and gradual, but they are nonetheless vital for the kingdom's advancement.
