“Let us ask ourselves what we know of this repentance and faith. Have we felt our sins, and forsaken them? Have we laid hold on Christ, and believed? We may reach heaven without learning, or riches, or health, or worldly greatness. But we shall never reach heaven, if we die impenitent and unbelieving. A new heart, and a lively faith in a Redeemer are absolutely needful to salvation. May we never rest till we know them by experience, and can call them our own! With them all true Christianity begins in the soul."
