You are presuming this is biblical. It's not.
Yes it is.
Eph 1:13-14 And you also were included in Christ when you heard the message of truth, the gospel of your salvation.

Eph 1:3-5 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4For he chose us in him before the creation of the world to be holy and blameless in his sight. In love 5he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will.
Luke 18:9-12 To some who were confident of their own righteousness and looked down on everyone else, Jesus told this parable: 10“Two men went up to the temple to pray, one a Pharisee and the other a tax collector. 11The Pharisee stood by himself and prayed: ‘God, I thank you that I am not like other people—robbers, evildoers, adulterers—or even like this tax collector. 12I fast twice a week and give a tenth of all I get.’
Luke 15:7 I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent.

Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men 10nor thieves nor the greedy nor drunkards nor slanderers nor swindlers will inherit the kingdom of God. 11And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.

Eph 2:4-9 But because of his great love for us, God, who is rich in mercy, 5made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved. 6And God raised us up with Christ and seated us with him in the heavenly realms in Christ Jesus, 7in order that in the coming ages he might show the incomparable riches of his grace, expressed in his kindness to us in Christ Jesus. 8For it is by grace you have been saved, through faith—and this is not from yourselves, it is the (gift) of God— 9not by works, so that no one can boast.
1 Cor 1:21 For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.
James 1:6-8 But when you ask, you must believe and not doubt, because the one who doubts is like a wave of the sea, blown and tossed by the wind. 7That person should not expect to receive anything from the Lord. 8Such a person is double-minded and unstable in all they do.
2 Tim 2:11-13 Here is a trustworthy saying: If we died with him, we will also live with him; 12if we endure, we will also reign with him. If we disown him, he will also disown us; 13if we are faithless, he remains faithful, for he cannot disown himself.

Rev 21:1-3 Then I saw “a new heaven and a new earth,”a for the first heaven and the first earth had passed away, and there was no longer any sea. 2I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God.
Heb 10:10-12 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all. 11Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. 12But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God.
Heb 10:22-23 let us draw near to God with a sincere heart and with the full assurance that faith brings, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. 23Let us hold unswervingly to the hope we profess, for he who promised is faithful.

Huh? That's not logical at all. If you never leave your wife, she can never leave you. Doesn't make sense to me.
How does a person show that he has a true faith? How do you show your true faith?
Your wife is not the Holy Spirit, the Holy Spirit is perfect in his will. Your wife is not. You show your faith by living by the Word of God.
