What we have done out of love to Christ; what we have offered through His mediation; what has been perfumed by faith in His Person becomes acceptable! God looks upon anything we say, or anything we do, and if He sees Christ in it, He accepts it; but if there is no Christ, He puts it away as a foul thing. See to it then, Beloved, that you never pray a prayer which is not sweetened with Christ. I would never preach a sermon—the Lord forgive me if I do—which is not full to overflowing with my Master.
