When we go to Christ for healing, faith eyes him peculiarly as one pierced. Faith takes several views of Christ, according to the occasions of address to him and communion with him that it hath. Sometimes it views his holiness, sometimes his power, sometimes his love, [sometimes] his favour with his Father. And when it goes for healing and peace, it looks especially on the blood of the covenant, on his sufferings; for “with his stripes we are healed, and the chastisement of our peace was upon him,” Isa. 53:5.
