“God offers [forgiveness] on the understanding that your sin deserved his wrath and curse, and that even his own Son’s Godhead and holiness and value in his sight could not exempt him, standing in your place, from having to bear that wrath and curse instead of you. Christ, by the sacrifice of his death, puts away sin…. You, while defending and excusing yourself, are labouring to put away the law.”

“True confession is taking guilt to ourselves before God.”

From “Christ for us”, sermons of Hugh Martin, p40-41.
