John Piper on Singleness

Single in Christ: A Name Better Than Sons and Daughters
"My main point is that God promises those of you who remain single in Christ blessings that are better than the blessings of marriage and children, and he calls you to display, by the Christ-exalting devotion of your singleness, the truths about Christ and his kingdom that shine more clearly through singleness than through marriage and childrearing."

Sex and the Single Person
"If the Bible addresses an issue with unrelenting frequency and urgency, and if that issue is one of the strongest natural forces in
the world today, then ministers of the Word of God are obligated sooner or later to declare God's will on that issue. The sexual life of the unmarried person is of great concern to God."
