Matthew 13:31-32, Mark 4:30-32, Luke 13:18-19
So many of us know the parable of the mustard seed that Jesus speaks of in Matthew 13:31-32. "Another parable put he forth unto them saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs,and becometh a tree, so the birds of the air come and lodge in the branches thereof." This parable is also referenced other times in the Bible.
Over my lifetime, I have heard many people say "You just need the faith of a grain of mustard, just that tiny seed." After doing some research on the mustard seed, it's actual size is one to two millimeters in diameter. If you take a look in your spice rack, you may even be able to see that for yourself. But, Jesus doesn't stop with the seed. He says it is suppose to grow much bigger into a tree, just like the kingdom of heaven.
The mustard seed actually grows into a tree about nine feet tall with very strong roots.
My challenge is the question, don't we need to grow that mustard seed? How do we do that? First, we can grow our own faith every day by reading and studying God's word and praying so that seed doesn't stay tiny. It is also our responsibility to grow the kingdom of heaven through witnessing to others and sowing seeds in others lives and investing in people!
What about when things come up in our lives unexpected or inconvenient that could potentially cause us to question our faith or derail our mission to see others saved? Does our seed just die out? Jesus talks trees again in John 15:5 "I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit; for without me ye can do nothing." These are the exact times in our lives we can grow that mustard seed even more. We have a responsibility every day to grow the kingdom of heaven, but what an opportunity to show others our growing faith in troubled times by looking only to Jesus.
I know my desire is for the mustard seed to become that large, nine foot or more tree bearing lots of fruit with strong roots. Although life is not always easy, we have the answers in the word of God. I will leave you with one last verse that sums this thought up for me : Matthew 12:33, "Either make the tree good, and his fruit good; or else make the tree corrupt: for the tree is known by his fruit."
