Are we planting seeds in the desert?

We often hear our job is to plant seeds and another will water and God will give the increase, but when we plant a seed, before we do, we labor to cultivate the soil, to fertilize it and to protect it. When one waters they seek the water and either fetch it, or dig a well or build reservoirs or make irrigation ditches, We labor we are engaged, we are personally involved. We don't walk through the barren soil sticking seeds where there is little or no chance of it growing; does not the parable of the sower teach us so? Evangelism without love is planting in the desert. All the Bible teaches us that, "They that sow in tears shall reap in joy." Evangelism, in general, is personal, and without love will be in vain.
