That same day Jesus went out of the house and sat by the lake. 2 Such large crowds gathered around him that he got into a boat and sat in it, while all the people stood on the shore. 3 Then he told them many things in parables, saying: “A farmer went out to sow his seed. 4 As he was scattering the seed, some fell along the path, and the birds came and ate it up. 5 Some fell on rocky places, where it did not have much soil. It sprang up quickly, because the soil was shallow. 6 But when the sun came up, the plants were scorched, and they withered because they had no root. 7 Other seed fell among thorns, which grew up and choked the plants. 8 Still other seed fell on good soil, where it produced a crop—a hundred, sixty or thirty times what was sown. 9 Whoever has ears, let them hear.”
Martin Luther said, “All this is spoken for our instruction, that we may not go astray, since so many misuse the Gospel and few lay hold of it aright. True it is unpleasant to preach to those who treat the Gospel so shamefully and even oppose it. For preaching is to become so universal that the Gospel is to be proclaimed to all creatures, as Christ says in Mk. 16:15: “Preach the Gospel to the whole creation;” and Ps. 19:4: “Their line is gone out through all the earth, and their words to the end of the world.” What business is it of mine that many do not esteem it? It must be that many are called but few are chosen. For the sake of the good ground that brings forth fruit with patience, the seed must also fall fruitless by the wayside, on the rock and among the thorns; inasmuch as we are assured that the Word of God does not go forth without bearing some fruit, but it always finds also good ground; as Christ says here, some seed of the sower falls also into good ground, and not only by the wayside, among the thorns and on stony ground. For wherever the Gospel goes you will find Christians. “My word shall not return unto me void” (Is. 55:11).
I have been cogitating upon this ears and hearing statement. It is used seldom in the Bible but when it is it is important. It is used only by Jesus and then in connection to some important things.
