Expositor's Bible Commentary Commentary Luke 14:28

"For which of you, desiring to build a tower, doth not first sit down and count the cost, whether he have [wherewith] to complete it?" — Luke 14:28 (ASV)

Jesus uses two different circumstances to illustrate his basic point: discipleship requires a conscious advance commitment, made with a realistic estimate of the ultimate personal cost. The practical nature of the circumstances Jesus so vividly pictures underlines the fact that Christian discipleship is not some theoretical abstract ideal but hard reality.
