Jesus demands full commitment and the renunciation of all things. God gives salvation in Jesus as a free gift, but it costs us everything. To this end we all do well to count the cost to see whether we will follow the Lord and obtain life or turn aside in our own ways unto death.
Now there went with him great multitudes: and he turned, and said unto them, “If any man cometh unto me, and hateth not his own father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. Whosoever doth not bear his own cross, and come after me, cannot be my disciple.
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? Lest haply, when he hath laid a foundation, and is not able to finish, all that behold begin to mock him, saying, ‘This man began to build, and was not able to finish.’
Or what king, as he goeth to encounter another king in war, will not sit down first and take counsel whether he is able with ten thousand to meet him that cometh against him with twenty thousand? Or else, while the other is yet a great way off, he sendeth an ambassage, and asketh conditions of peace.
So therefore whosoever he be of you that renounceth not all that he hath, he cannot be my disciple (Luke 14:25-33).
