Deep roots are essential in times of drought
Growing up on a farm in Saskatchewan taught me the importance of roots going deep. In the Prairies, rain is very unpredictable and with dryland farming, rain is also an absolute necessity in summer. If during those hot, dry, dusty summer months, weeks went by without rain, the concern became palpable. Farmers would mention rain as a prayer request at every prayer meeting. My grandfather would call us early in the morning to find out if the latest rainshower had hit our farm or not.
But if the crop had developed deep roots in the early part of the growing season, it could survive even a month or longer without rain. Roots grow toward the water. Even if the top few inches of the ground are dry, the crop can survive by drawing on those resources well below the surface. The roots of wheat can grow to a depth of 1.5 meters, but they can’t grow through bone-dry dirt and their growth is impeded by compacted soil. So during spring seeding, the soil must have sufficient moisture and be loose enough to allow those seeds to germinate and to send their roots down to the level of the moisture.
A few days ago in my NT Bible reading in Mark 4, I read about the seed that is sown on rocky soil.
Others, like seed sown on rocky places, hear the word and at once receive it with joy. But since they have no root, they last only a short time. When trouble or persecution comes because of the word, they quickly fall away. – Mark 4:16–17, NIV
If the seed of the Word of God falls on rocky soil, the roots will not go deep. Lack of deep roots evidently means that a person does not have the faith that sustains them through times of hardship, distress, or opposition. When times become difficult and they are criticized for their faith, their commitment to following Jesus quickly wanes.
