The parable of the sower explains why the Word of God does not produce the fruit it must bear in the life of a Christian. In summary, it says that the Word of God must be given the right conditions in order to be effective. Just as a seed, when placed in unfavorable conditions would not grow and bear fruit, the Word of God, would not fulfill its purpose when improperly received.
The Lord Jesus is considered the greatest man who ever lived because of His Words and Deeds. Of course, for us Christians, He is God. His Word is essential to us. His Word is a must for us. But it is also a fact that even non-Christians hear and believe in His Word. His Word penetrates the heart of any person, believer or not.
But He was not only known for His Word. His Word finds fulfillment in His Deed. The Lord Jesus has set an example. Words are not enough. Deeds should compliment them. Unless the Word of the Lord is put into action by believers, it can not give the benefit Jesus promised with it. Words point to actions and realities. They can not remain as a combination of letters or an utterance. They must find a home in our actions. Words only has meaning when put into action.
It follows then that the best condition for the Word of God is by acting on it. More specifically, by living it. What is heard must be understood, reflected , and lived. Only when it is lived will it be able to produce and bear fruit in the our lives. It is clear then that for the Lord Jesus, salvation is more than the spoken and heard Word of God. Salvation is attained in the lived Word of God.
