Two verses came to my mind when I was asked this question:

Deuteronomy 24:1-4
1 “When a man takes a wife and marries her, if then she finds no favor in his eyes because he has found some indecency in her, and he writes her a certificate of divorce and puts it in her hand and sends her out of his house, and she departs out of his house,
2 and if she goes and becomes another man’s wife,
3 and the latter man hates her and writes her a certificate of divorce and puts it in her hand and sends her out of his house, or if the latter man dies, who took her to be his wife,
4 then her former husband, who sent her away, may not take her again to be his wife, after she has been defiled, for that is an abomination before the Lord. And you shall not bring sin upon the land that the Lord your God is giving you for an inheritance. ESV

1 Corinthians 7:27 Are you bound to a wife? Do not seek to be free. Are you free from a wife? Do not seek a wife. ESV

But I read lots of articles and sermons concerning the matter about remarriage. However my intitial thoughts were not changed but confirmed. Whether or not you believe that there are valid Biblical reasons for divorce, there seems to be no valid Biblical reason for leaving a second spouse to return to the first.

What is the status of a Christian who divorces without biblical grounds and remarries? Is he living in perpetual adultery? What about the concept of forgiveness? If someone has remarried unbiblically and seek forgiveness, is he forgiven?

In Matthew 5:31-32, Jesus says, “It has been said, ‘Whoever divorces his wife, let him give her a certificate of divorce.’ But I say to you that whoever divorces his wife for any reason except sexual immorality causes her to commit adultery; and whoever marries a woman who is divorced commits adultery.”

Jesus is saying that the act of remarriage is an act of adultery. He is not teaching that the ongoing conjugal relationship with the new spouse is a state of “perpetual adultery”–as if God refused to recognize the remarriage as legitimate in any sense.

If that were the case–if the ongoing physical relationship between the remarried couple constituted one long, continuous, adulterous affair—the proper remedy, and the only way to end the chain of adultery, would be to dissolve the second marriage and insist that everyone return to his or her original spouse. On the contrary, Scripture teaches that the new marriage is now binding. In order to avoid further acts of adultery, the remarried person needs to remain faithful to the new spouse.

As a matter of fact, in the same passage where Moses permitted husbands to issue a certificate of divorce, the law added this restriction: “When she has departed from his house, and goes and becomes another man’s wife, if the latter husband detests her and writes her a certificate of divorce, puts it in her hand, and sends her out of his house, or if the latter husband dies who took her as his wife, then her former husband who divorced her must not take her back to be his wife after she has been defiled; for that is an abomination before the LORD” (Deuteronomy 24:2-4, emphasis added).

Clearly, the second marriage—whether biblically justified or not—becomes as binding as the original marriage was supposed to be. A return to the original spouse is strictly forbidden.

So Jesus’ words in Matthew 5:32 (and Mark 10:11-12) mean simply that entering into an illegitimate remarriage is an adulterous act. Nevertheless, once that new marriage covenant is sealed, the remarried couple needs to remain married and be faithful to one another. Their on going physical relationship is not to be thought of as “perpetual adultery.”

On the other hand, as long as they remain unrepentant about the illegitimate remarriage, they cannot expect God’s blessing on their marriage. Like all sins, that unauthorized remarriage must be confessed and repented of.

Because marriage entails a covenant that God deems holy, any remarriage (even remarriage after an unbiblical divorce) cannot be—and should not be—forsaken as we would forsake virtually any other sin. But people who have entered into such a relationship do need to seek God’s forgiveness with sincere repentance.

And yes, God does grant forgiveness for such sins to those who seek His pardon in Christ.

John Piper says:

Those who are already remarried:

1. Should acknowledge that the choice to remarry and the act of entering a second marriage was sin, and confess it as such and seek forgiveness

2. Should not attempt to return to the first partner after entering a second union.

3. Should not separate and live as single people thinking that this would result in less sin because all their sexual relations are acts of adultery. The Bible does not give prescriptions for this particular case, but it does treat second marriages as having significant standing in God’s eyes. That is, there were promises made and there has been a union formed. It should not have been formed, but it was. It is not to be taken lightly. Promises are to be kept, and the union is to be sanctified to God. While not the ideal state, staying in a second marriage is God’s will for a couple and their ongoing relations should not be looked on as adulterous.
