Luke 14:26-33, “If anyone comes to me and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be my disciple. 27 Whoever does not bear his own cross and come after me cannot be my disciple. 28 For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it? 29 Otherwise, when he has laid a foundation and is not able to finish, all who see it begin to mock him, 30 saying, ‘This man began to build and was not able to finish.’ 31 Or what king, going out to encounter another king in war, will not sit down first and deliberate whether he is able with ten thousand to meet him who comes against him with twenty thousand? 32 And if not, while the other is yet a great way off, he sends a delegation and asks for terms of peace. 33 So therefore, any one of you who does not renounce all that he has cannot be my disciple.”
Christianity is far more than accepting a series of statements about Jesus. We may believe everything there is to believe about Christ, and admit that we are sinners in need of his salvation—but this does not make us Christians.
The reality is that every person must make an actual response to the Gospel about Jesus and salvation. That response is not a mere intellectual agreement. It is a response that involves repentance, faith, and a willingness to follow Jesus. That response involves committing ourselves totally to Him as our Savior and Lord.
In our passage, Jesus notes that anyone setting out to build a tower would first count the cost to make sure they had the resources to finish the tower. After all, what good is a half-built tower? Such a useless building would only result in ridicule for the one who failed to count the cost. Likewise, Jesus urged people to count the cost of discipleship before they make the commitment to be a Christian.
