theres this great preacher named David Pawson!! he has many messages that explain even the most confusing topics so they are easy to understand!! he has a website. davidpawson.org i think. but you can google his name and his website will appear. anyways he has a message about divorce that really makes sense.
Divorce is spiritually impossible, according to Jesus (Mk 10:1-12). It is not merely "against the rules." It is like trying to repeal the law of gravity, not like trying to repeal a parking ticket. Jesus' command against seeking divorce is not an arbitrary "rule," but rather a comment on what marriage actually is. A valid marriage is simply not capable of being dissolved. A validly married couple who divorce may THINK their action ended their marriage before God and in the eyes of the Church, but that is not true. They are still married (Rom 7:2-3; 1 Cor 7:10-11). Divorce and remarriage violate natural divine laws. They break the covenant to which spouses freely consented - namely to live with each other until the death of one of them. Divorce also introduces disorder into the family and into society as a whole. This can bring great harm to one or both of the spouses and certainly to the children.
