"It makes no sense to have the mustard seed if you aren't going to trust that when you plant it, something will grow."
I then thought of the Matthew 17:20: "He replied, “Because you have so little faith. Truly I tell you, if you have faith as small as a mustard seed, you can say to this mountain, ‘Move from here to there,’ and it will move. Nothing will be impossible for you.” (NIV). From there my thoughts wandered to a farmer getting ready to plant his year's crop. He labors intensely to prepare the soil, plant the seeds, water the ground, etc. When he is finished, he waits patiently for the harvest. While I haven't spend much time on a farm (ok, none), I know that farmers do not plant crops and then dig them up the next day to see if anything is happening. They wait.
Impatience does not equal progress, only regrets. What good would it do to plant a seed and not allow it to grow? Soil is brown for a reason. If we starred at a clear cup full of soil and one mustard seed, we would loose focus on the reason that mustard seed is growing. Farmers monitor their crops, they do not hover over them 24/7. They give the crops space to grow and trust that the seeds will blossom and grow into something wonderful.
Our faith should be no different than the seeds a farmer grows. If we say we love God, then we ought to trust that He will take care of us. Our faith must be firmly planted like the seed is in the soil. All we need to do is be patience during the growth process and wait for God to tell us when it is harvest time. Just as the farmer tends to the crops, watering them, removing weeds, scaring off birds, we too must tend to our faith. We must nourish it with the Word of God, remove those things which can cause us to stumble and kill our faith, and protect it from harmful toxins (people, places, and things).
We may start out with a mustard seed, but come harvest time, we shall have a stronger, deeply rooted, loving, generous, faith in God. God gives us the tools we need in this life. It is up to us to learn how to use them and mature as we do.
