From the way that article reads, Not really. Now Marriage is about preserving the next generation? That's not a bad idea, but how about preserving the vows YOU commited to. How about Preserving not just your children but the right kind of values they will need to bring up another generation. How about putting God back at the head of the family and letting him dictate what our minds find to be stimulating.
God alone is the hope for the American marraige. Not a pleadge to take care of the kids, not a pledge to care for your spouse, not even a commitment to love just one person. These things will keep a union together, but do not necessarily mean that they will make that union worth anything. Only by adding God and his teachings into the union can we expect to see Marraige survive.
