Christian view on divorce

In Australia, every third marriage ends in divorce. During the past two decades, Australians started to marry less and divorce more. About one-third of children today are born outside the traditional marriage. Divorced people have a higher chance of re-marriage than those who are widowed - nearly half of divorced people re-marry. About three-quarters of people who marry today lived with their partner for some time prior to marriage. The divorce rate in Australia per 1000 of population remains around the level of 2.5% (plus-minus 0.2%) since 1988, as well as the average number of children per divorce of 1.88

Let's take a look at what the Bible says about divorce and remarriage. Most Christians who favor divorce try to justify their view by arguing that God allowed divorce (Duet 24:1-3) in the law. They proceed to argue that since God is never changing, then he must allow divorce now. However, we must not jump to conclusion based on one or two individual verses in the Bible, but should look at its teaching as a whole. Based on 1Corinthians 7:10-11, 1Corinthians 7:27, Matthew 19:6 and Mark 10:9, it is clear that God dislikes divorce (to the extent that He used the word hate). Christ said, 'What God has joined together, let not man separate' (Matthew 19:6). Why did Moses allow divorce in the Old Testament then (Duet 24:1-3)? Did God contradict Himself, or did he change his mind? If we read Mark 10:5, we learn that Moses allowed divorce because the Israelites hearts were hardened, much like Pharaohs heart was hardened when the Israelites tried to leave Egypt (Ex 4:21 and Ex 10:20). Just because God allowed Pharaoh and those who desire divorce to harden their hearts, does it mean that He supported what they did? Certainly not! By the same token, God allows sins to occur too, but that does not mean He ordains these actions

Biblical reasons for divorces 

Adultery: Jesus said, "And I say to you, whoever divorces his wife, except for immorality, and marries another woman commits adultery," (Matt. 19:9). The word in Greek for immorality is porneia from which we get the word pornography.  Sexual immorality, i.e., adultery, is a grounds for divorce according to Jesus.

Abandonment: In addressing the issue of husband and wife, Paul said, "Yet if the unbelieving one leaves, let him leave; the brother or the sister is not under bondage in such cases, but God has called us to peace," (1 Cor. 7:15).
