A favorite book on marriage.
Some favorite quotes:
"The one thing that discontented people cannot do is give thanks, and therefore they cannot have the wisdom that contentment brings."
"From a thankful heart, all things may be received, including the great gifts of discipline and standards (1Tim 4:4-5). But without gratitude pervading everything, strict views on marriage will simply create an earthly hell for yourself and others."
"A godly marriage occurs when a man and a woman both die to themselves, and are raised to the life that seeks the best interest of the other in all things. This is the only kind of godly marriage there is. And when we give all away in this manner, we discover that we receive all."
