Yet those who marry will have worldly troubles, and I would spare you that. This is what I mean, brothers: the appointed time has grown very short. From now on, let those who have wives live as though they had none... (1 Cor 7:28, 29 ESV)
There is much benefit in raising children, one being that we have someone to take care of us when we get old. Did Paul overlook this need of the elderly because of his belief that the coming of the Lord is imminent and that the Corinthians may not reach old age anyway?
My concern is on the practical application of Paul's advice. Not getting married is a pivotal decision, and Paul's advice is one that speaks directly on the matter.
