Donald Cargill was a Scottish clergyman and a prominent Covenanter during the 17th century. He was known for his strong opposition to the religious policies of the Scottish Crown and his efforts to promote Presbyterianism. Cargill's activism and leadership in the Covenanter movement played a significant role in the religious and political history of Scotland. His commitment to his faith and his contributions to the religious landscape of his time have left a lasting impact.

"I have followed holiness, I have taught truth, and I have been most in the main things; not that I thought the things concerning our times little, but that I thought none could do anything to purpose in God's great and public matters, till they were right in their conditions."

"I cannot but be grieved to go from my native land, and especially from that part of it for whom and with whom I desired only to live; yet the dreadful apprehensions I have of what is coming upon this land may help to make me submissive to this providence, though more bitter."

"It is long since I could have adventured on eternity, through God's mercy and Christ's merits; but death remained somewhat terrible, and that now is taken away; and now death is no more to me, but to cast myself into my husband's arms, and to lie down with Him."

"Farewell, dearest friend, never to see one another any more till at the right hand of Christ."

"I have been a man of great sins, but He has been a God of great mercies; and now, through His mercies, I have a conscience as sound and quiet as if I had never sinned."

"Now for my own case, I bless the Lord that, for all that hath been said of me, my conscience doth not condemn me. I do not say I am free of sin, but I am at peace with God through a slain Mediator; and I believe that there is no salvation but only in Christ."

"But go on, valiant champion; you die not as a fool, though the apostate, unfaithful, and lukewarm ministers and professors of this generation think and say so."
