Here’s a quote attributed to Traill, in the Gospel Standard magazine (March 2006). It’s short on purpose cos something funny’s been going on with the internet connection here.
What should a sinner do but go to Christ? What can come of a sinner if Christ receive him not? Yea, what is a Saviour of sinners for, but for receiving sinners and saving them from their sins? … [However] no one can see any glory in that grace of Christ which he has no sight or sense of his own need of.
Robert Traill was a Covenanter (I think) and the Banner of Truth has republished at least some of his writings.
