Keep God’s covenant in your trials. Hold you by His blessed word, and sin not. Flee anger, wrath, grudging, envying, fretting. Forgive an hundred pence to your fellow-servant, because your Lord hath forgiven you ten thousand talents. For I assure you by the Lord, your adversaries shall get no advantage against you, except you sin and offend your Lord in your sufferings.
Letters of Samuel Rutherford (Edinburgh: Oliphant, 1891), 57–58.
