Jesus once told a story comparing the human heart to a farmer’s field (Matthew 13:1-13). Some hearts are flat and hard. Some are shallow and rocky. Others are cluttered with the cares of this world, and like thorns, choke the sower’s seed before it has a chance to grow.
The world, the flesh, and the devil work overtime to make sure that when the word of God falls on our hearts like a seed, it never springs forth nor yields a bountiful harvest.
That’s why we must guard our hearts as a farmer cultivates his soil, by guarding the gateways to the human heart. Guard your eyes (what you look upon), your ears (what you hear), and your mind (what you think about).
