The picture is a simple one, and it is fairly clear. When the regular straightforward man is engaged on his smallholding, what does he do it for? Why does he get up early in the morning, milk his animals, tend to his flock, why does he go about the fields, do all that work? It was very hard work in the old days.
What are words for? What is Christian fellowship for? What is the purpose of my being set among ungodly people, who are not yet saved in my place of work or college? It is to care, to witness, to be beneficial, to sustain and advance life, and particularly spiritual life. What a responsibility I now have to control my words, to direct my words, advance with greater skill in the use of words, have greater knowledge, so that I can control my words, and say the best words.
