Jesus said that a man leaves his father and mother (first marriage) and is joined to his wife and the two become one flesh. So, they are no longer two but one flesh. This is more than legal marriage and Jesus wanted to make it clear that they were no longer two but one flesh. This is a holy union that God participates in and enters into covenant with the two parties.
The following from the Word of God will show that divorce does not unjoin in any way what God has joined. Man may separate, and he does, but man cannot unjoin. Man does not have the power to take what God has made “One flesh” and make it two flesh again.
1. Death, not divorce ends what God joins according to 1 Corinthians 7:39 (ESV). A wife is bound to her husband as long as he lives. But if her husband dies, she is free to be married to whom she wishes, only in the Lord. The Apostle Paul did not believe that divorce ended the first marriage.
2. This passage teaches the same thing and makes it clear that the first marriage is a union that is still joined by God by declaring that a second marriage is adultery. Romans 7:2-3 (KJV) — For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband. So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man. The Apostle Paul did not believe that divorce and even marriage after divorce ended the first marriage.
3. The following passage states two times that marriage after divorce is adultery. This means that the first marriage is still a union joined by God. In Matthew and Mark there are five other times that similar statements are made. Luke 16:18 (ESV) — Everyone who divorces his wife and marries another commits adultery, and he who marries a woman divorced from her husband commits adultery. As a side note, God would never participate in a wedding where the result was adultery. He would not take two flesh and make one flesh if one of the participants is still “one flesh” with a former spouse. Jesus did not believe that divorce or marriage after divorce ended the first marriage. In fact, these passages teach the exact opposite. For marriage after divorce to be adultery, the person still has to be joined to their first spouse.
4. Malachi 2:14 (ESV) speaks to a man who had divorced the wife of his youth (first marriage). He likely had married at least once since. God says He is still standing as a witness against this man and refuses to accept the offering from his hand. God does not believe that divorce ended the first marriage. “But you say, “Why does he not?” Because the LORD was witness between you and the wife of your youth, to whom you have been faithless, though she is your companion and your wife by covenant.
5. Jeremiah 3 speaks of God divorcing Israel for all of her harlotries and idolatry. Later in the same chapter He calls her back to Him as His “wife” after He divorced her. We know that thousands of years later He is still waiting for His wife Israel to return and that someday she will return to Him. Also, Malachi 2 speaks to the same issue only it states that Israel has “married the daughter of a foreign god.” God still wants her back and is waiting for His wife Israel to return. God initiated this divorce due to her behavior, but He does not believe that it ended the union that He created.
6. John the Baptist (Matthew 14:1-12 and Mark 6:14-29) did not believe that divorce ended a first marriage. He kept declaring publicly that King Herod was not allowed to have the wife he was living with (Herodias). These passages refer to Herodias, King Herod’s current partner, as the wife of his brother, her prior husband. Due to his boldness and courage for the fact that he did not believe that divorce ended the first marriage, he had his head removed and served up on a platter as a trophy at a birthday party for the King.
7. King David did not believe that divorce ended his union with his first wife Michal. 2 Samuel 3 tells the story of David wanting his first wife back more than political power. He forced her to be divorced from her second husband who loved her and brought back to him. Compare 1 Kings 15:5. There are two or three Scripture passages that those who would have you believe that divorce unjoins what God joins would try to use, but none that actually say that. The bigger question that begs to be asked is why anyone would want to believe that divorce unjoins what God joins.
Will you believe and follow Jesus, the Apostle Paul, John the Baptist, the prophet Malachi, King David, God himself and the Word of God? When I understand, believe and obey God’s truth it enables me to keep on in this journey. God’s truth always wins.
God bless.
