Luk 14:25-35 And there went great multitudes with him: and he turned, and said unto them, (26) If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. (27) And whosoever doth not bear his cross, and come after me, cannot be my disciple. (28) For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it? (29) Lest haply, after he hath laid the foundation, and is not able to finish it, all that behold it begin to mock him, (30) Saying, This man began to build, and was not able to finish. (31) Or what king, going to make war against another king, sitteth not down first, and consulteth whether he be able with ten thousand to meet him that cometh against him with twenty thousand? (32) Or else, while the other is yet a great way off, he sendeth an ambassage, and desireth conditions of peace. (33) So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple. (34) Salt is good: but if the salt have lost his savour, wherewith shall it be seasoned? (35) It is neither fit for the land, nor yet for the dunghill; but men cast it out. He that hath ears to hear, let him hear.
Paul is an example of one who forsook all. He was a Jew of Jews, Pharisee of Pharisees, as zealous as they come for the culture that he adhered to, but he recognized that what Christ offered to Him by faith in Him was worth loosing all the "tenure" that he had built up in the system he was raised in:
Gal 1:9-16 As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. (10) For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ. (11) But I certify you, brethren, that the gospel which was preached of me is not after man. (12) For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ. (13) For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it: (14) And profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers. (15) But when it pleased God, who separated me from my mother's womb, and called me by his grace, (16) To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:
Christ, loving us, calls us to forsake all, and follow. Paul thought that it was a "good bet" to give up his station in life, and the presuppositions and values of the elite culture of the Pharisees in order to place his faith in Christ, and to cease to trust the "merit" he had attained by his previous high standing among his peers.
I propose that it is a way of loving our wives to lead them to Christ, and turning from our trust in what we have received, if what we have received is not Christ and his Kingdom.
