Thomas Halyburton, The Great Concern of Salvation (Works, p. 107):
I cannot now enter upon the consideration of many other pretences, whereby sinners shelter themselves from convictions; only I wish ye may rivet upon your hearts three truths, which will help to preserve you from laying weight upon them. (1.) Be persuaded, that there are but few that will be saved. Christ has said so, and who dare give him the lie? (2.) Believe it, they who shall be saved, shall not be saved in an easy way. The “righteous are scarcely saved,” 1 Pet. 4:18. (3.) Ye are to endeavour a solid conviction, that there is no salvation for you, but in the gospel-way, Acts 4:12. Understand and believe these three truths, and this will be a mean to preserve you from a reliance upon things that cannot profit.
