“For which of you, intending to build a tower, does not sit down first and count the cost, whether he has enough to finish it” (Luke 14:28).
Jesus underlines the importance of counting the cost of discipleship. Many people make impulse purchases without even considering the cost, or they rush into marriage or a career. Sadly, some do the same in their commitment to follow Christ.
This point is illustrated in Luke 9:57–58: “Now it happened as they journeyed on the road, that someone said to Him, ‘Lord, I will follow You wherever You go.’ And Jesus said to him, ‘Foxes have holes and birds of the air have nests, but the Son of Man has nowhere to lay His head.'”
The man in this story did not even wait to be called. He hastily volunteered. He seemed to have a good heart, but he was impulsive. No doubt he had been watching Jesus with great admiration, and now wanted to walk with Him. But he had not counted the cost!
This man did not know what lay in his future, but Jesus did. By the nature of Jesus’ statement to him, it would appear that this man, in contrast to the one who wanted to avoid friction with family and friends, was too concerned with material things in general. In essence, Jesus was saying to this man (and to all who would be His disciples), “Whatever would dull your desire to serve, quench your hunger for the Word and thirst for prayer, or make the world more attractive must go.”
Jesus is not asking if you will commit 20%, 30%, or 50% to Him. He is asking you to commit everything. Billy Graham has said, “Salvation is free, but discipleship costs everything we have.”
