When my kids were young, we had a hot tub that had hundreds of air holes that would bubble up to make it relaxing. One day, someone got the bright idea to squeeze a little dish soap in it while it was bubbling. It seemed like and insignificant amount, but before I knew it, the hot tub was bubbling up to over six feet high! It eventually filled the pool that was connected to it. It was a beautiful sight, and the kids had a blast frolicking in the suds.
The message of Jesus has spread, and continues to go throughout the world, growing quietly, without those who are against it being able to stop its progression, just like the drops of dish soap in the hot tub. Jesus makes a couple of comparisons in the book of Luke; one being like a tiny mustard seed that grows into a tree, and one like yeast in dough. The kingdom of God cannot be stopped, no matter how hard the enemy tries! His kingdom will not be overcome by the powers of darkness, and will live long into eternity. That is the community you are a part of!
He said therefore, “What is the kingdom of God like? And to what shall I compare it? It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree, and the birds of the air made nests in its branches.” And again he said, “To what shall I compare the kingdom of God? It is like leaven that a woman took and hid in three measures of flour, until it was all leavened.” Luke 13:18-21
