I sometimes wonder that you do not get tired of my preaching, because I do nothing but hammer away on this one nail. With me it is, year after year, ‘None but Jesus!’ Oh, you great saints, if you have outgrown the need of a sinner’s trust in the Lord Jesus, you have outgrown your sins, but you have also outgrown your grace, and your saintship has ruined you!
