Marriage, Divorce And Remarriage By Kenneth E. Hagin

Many Christians and even Pastors, because of lack of awareness of how God sees remarriage, tend to condemn many who were separated or divorced and remarry, as men or women who are sinful and that they do not have the right to be in God's Kingdom. This is highly recommended for Pastors and Christians who think people like them are still sinning despite their having remarried again. 
Separation and divorce hurt everyone, and God protects married couple from unnecessary hurt and pain. Unfortunately, married people change, or may have married with a wrong reason, or may be despite their efforts to protect their marriage, their marriage doesn't really work, or may be they are simply victims of people who have not really learned to love unconditionally. This book is a great enlightenment for people who have missed the idea that God is love and God of many chances. 
He does not allow divorced people to be condemn all their lives but instead He allows love for the second, or the ninth time. God is ever patient and loving and He knows exactly what people in our generation now need-- second chance or more, and lots of love.
