Today singleness is cherished by many because it brings maximum freedom for self-realization. You pull your own strings. No one cramps your style. But Paul cherished his singleness because it put him utterly at the disposal of the Lord Jesus …. The contemporary mood promotes singleness (but not chastity) because it frees from slavery. Paul promotes singleness (and chastity) because it frees for slavery—namely slavery to Christ.
John Piper
