“Can a married woman still live as though she were a single girl? Well, yes, I suppose she can. It is not impossible. But let her feel that ring on the fourth finger of her left hand, the symbol of her new life, the symbol of her identification with her husband, let her remember who she is, and let her live accordingly. Can a born-again Christian live as though he were still in his sins? Well, yes, I suppose he can. It is not impossible. But let him remember his baptism, the symbol of his identification with Christ in His death and resurrection, and let him live accordingly.”
John Stott
