The condition of our heart is one of the most vital aspects of our Spiritual life. When Jesus told the parable of the sower and the seed, the soil depicted the heart. There were those hearts of stone, which could not accept His teachings; the Word of God bouncing off them with nil effect.
There were those hearts that were shallow, and before the Word could take root, it was choked out by the distractions of the world.
Then there was the soft, deep heart into which the Word fell and grew; till it multiplied and bore much fruit.
However one thing that may go unnoticed is that the ground (heart) had first been prepared to accept the seed. No soil is loamy and good without having first been thoroughly weeded and turned by a trowel.
For God's Word to take effect in our hearts; for it to grow and bear much fruit in our lives, we must constantly be allowing Him to tend it by weeding out the things that hinder us, constrict us, or distract us. We must permit the Lord to turn over the soil of our hearts so He can know all of its depths, that His Word may take root, flourish and manifest itself in our lives as good fruit.
Are there placed in your heart that are overgrown and needing the tending of the Gardener?
