I find him proposing to a minister who was going up to the General Assembly that year, "that the Assembly should draw out a _Confession of Sin_ for all its ministers." The state, also, of parishes under the direful influence of Moderatism, lay much upon his spirit. In his diary he writes: "Have been laying much to heart the absolute necessity laid upon the church of sending the gospel to our dead parishes, during the life of the present incumbents. It is confessed that many of our ministers do not preach the gospel--alas! because they know it not. Yet they have complete control over their own pulpits, and may never suffer the truth to be heard there during their whole incumbency. And yet our church consigns these parishes to their tender mercies for perhaps fifty years, without a sigh! Should not certain men be ordained as evangelists, with full power to preach in every pulpit of their district,--faithful, judicious, lively preachers, who may go from parish to parish, and thus carry life into many a dead corner?" This was a subject he often reverted to; and he eagerly held up the example of the Presbytery of Aberdeen, who made a proposal to this effect. From some of his later letters, it appears that he had sometimes seriously weighed the duty of giving up his fixed charge, if only the church would ordain him as an evangelist. So deep were his feelings on this matter, that a friend relates of him, that as they rode together through a parish where the pastor "clothed himself with the wool, but fed not the flock," he knit his brow and raised his hand with vehemence as he spoke of the people left to perish under such a minister.
He was invited to visit Ireland again this year, his former visit having been much valued by the Presbyterian brethren there. He did so in July. Many were greatly stirred up by his preaching, and by his details of God's work in Scotland. His sermon on Song 8:5, 6, is still spoken of by many. His prayerfulness and consistent holiness left enduring impressions on not a few; and it was during his visit that a memorial was presented to the Irish Assembly in behalf of a Jewish mission. His visit was in a great measure the means of setting that mission on foot.
Cordially entering into the proposal of the concert for prayer, he took part, in September of this year, in the preliminary meetings in which Christians of all denominations joined. "How sweet are the smallest approximations to unity!" is his remark in his diary. Indeed, he so much longed for a scriptural unity, that some time after, when the General Assembly had repealed the statute of 1799, he embraced the opportunity of showing his sincere desire for unity, by inviting two dissenting brethren to his pipit, and then writing in defence of his conduct when attacked. In reference to this matter, he observed, in a note to a friend: "I have been much delighted with the 25th and 26th chapters of the _Confession of Faith_. Oh for the grace of the Westminster divines to be poured out upon this generation of lesser men!"
As it was evident that his Master owned his labor abundantly, by giving him seals of his apostleship, there were attempts made occasionally by zealous friends to induce him to remove to other spheres. In all these cases, he looked simply at the apparent indications of the Lord's will. Worldly interest seemed scarcely ever to cross his mind in regard to such a matter, for he truly lived a disinterested life. His views may be judged of by one instance,--a letter to Mr. Heriot of Ramornie, in reference to a charge which many were anxious to offer him:--
