How do we know counting the cost of discipleship is important?

In the same passage, Jesus uses vivid examples, such as a king assessing whether he can win a battle, to illustrate the necessity of evaluating one's readiness to follow Him. The call to 'count the cost' serves a dual purpose: it prepares potential disciples for the sacrifices ahead and serves as a guard against superficial or temporary commitments, which can lead to backsliding. Jesus sought to discourage those who might follow Him lightly out of emotional excitement rather than a sober understanding of what it means to be His disciple, emphasizing the importance of entering into a serious relationship with Him that requires commitment and perseverance.
