While he was at Kirkcudbright, he met with a young man in scarlet and silver lace (the gentleman's name was Mr. Robert Glendining) new come home from his travels, he much surprised the young man by telling him, he behoved to change his garb, and way of life, and betake himself to the study of the scriptures, which at that time was not his business, for he should be his successor in the ministry at Kirkcudbright, which accordingly came to pass sometime thereafter.
Mr. Welch was transported to Ayr in the year 1590, and there he continued till he was banished, there he had a very hard beginning, but a very sweet end; for when he came first to the town, the country was so wicked and the hatred of godliness so great, that there could not one in all the town be found, who would let him a house to dwell in, so he was constrained to accommodate himself the best he might, in a part of a gentleman's house for a time; the gentleman's name was John Stuart merchant, and sometime provost of Ayr, an eminent Christian, and great assistant of Mr. Welch.
And when he had first taken up his residence in that town, the place was so divided into factions, and filled with bloody conflicts, a man could hardly walk the streets with safety; wherefore Mr. Welch made it his first undertaking to remove the bloody quarrelings, but he found it a very difficult work; yet such was his earnestness to pursue his design, that many times he would rush betwixt two parties of men fighting, even in the midst of blood and wounds. He used to cover his head with a head-piece before he went to separate these bloody enemies, but would never use a sword, that they might see he came for peace and not for war, and so, by little and little, he made the town a peaceable habitation.
His manner was, after he had ended a skirmish amongst his neighbours, and reconciled these bitter enemies, to cause cover a table upon the street, and there brought the enemies together, and beginning with prayer he persuaded them to profess themselves friends, then to eat and drink together, then last of all he ended the work with singing a psalm: For after the rude people began to observe his example, and listen to his heavenly doctrine, he came quickly to that respect amongst them, that he became not only a necessary counsellor, without whose council they would do nothing, but an example to imitate.
He gave himself wholly to ministerial exercises, he preached once every day, he prayed the third part of his time, was unwearied in his studies, and for a proof of this, it was found among his papers, that he had abridged Suarez's metaphysics when they came first to his hand, even when he was well stricken in years. By all which it appears, that he has not only been a man of great diligence, but also of a strong and robust natural constitution, otherwise he had never endured the fatigue.
Sometimes, before he went to sermon, he would send for his elders and tell them, he was afraid to go to pulpit; because he found himself sore deserted: and thereafter desire one or more of them to pray, and then he would venture to pulpit. But, it was observed, this humbling exercise used ordinarily to be followed with a flame of extraordinary assistance: So near neighbours are many times contrary dispositions and frames. He would many times retire to the church of Ayr, which was at some distance from the town, and there spend the whole night in prayer; for he used to allow his affections full expression, and prayed not only with audible, but sometimes a loud voice.
There was in Ayr before he came to it, an aged man, a minister of the town, called Porterfield, the man was judged no bad man, for his personal inclinations, but so easy a disposition, that he used many times to go too great a length with his neighbours in many dangerous practices; and amongst the rest, he used to go to the bow-butts and archery, on the sabbath afternoon, to Mr. Welch's great dissatisfaction. But the way he used to reclaim him was not bitter severity, but this gentle policy; Mr. Welch together with John Stuart, and Hugh Kennedy, his two intimate friends, used to spend the sabbath afternoon in religious conference and prayer, and to this exercise they invited Mr. Porterfield, which he could not refuse, by which means he was not only diverted from his former sinful practice, but likewise brought to a more watchful and edifying behaviour in his course of life.
While Mr. Welch was at Ayr, the Lord's day was greatly profaned at a gentleman's house about eight miles distance from Ayr, by reason of great confluence of people playing at the foot-ball, and other pastime. After writing several times to him to suppress the profanation of the Lord's day at his house, (which he slighted, not loving to be called a puritan) Mr. Welch came one day to his gate and calling him out to tell him, that he had a message from God to shew him, that because he had slighted the advice given him from the Lord, and would not restrain the profanation of the Lord's day committed in his bounds; therefore the Lord would cast him out of his house, and none of his posterity should enjoy it: which accordingly came to pass; for although he was in a good external situation at this time; yet henceforth all things went against him until he was obliged to sell his estate; and when giving the purchaser possession thereof, he told his wife and children that he had found Mr. Welch a true prophet[49].
He married Elizabeth Knox, daughter to the famous Mr. John Knox minister at Edinburgh, and she lived with him from his youth till his death. By her he had three sons[50].
As the duty wherein Mr. Welch abounded and excelled most in his prayer, so his greatest attainments fell that way. He used to say, He wondered how a Christian could ly in bed all night, and not rise to pray, and many times he rose, and many times he watched. One night he rose from his wife, and went into the next room, where he staid so long at secret prayer, that his wife, fearing he might catch cold, was constrained to rise and follow him, and, as she hearkened, she heard him speak as by interrupted sentences, Lord, wilt thou not grant me Scotland, and after a pause, Enough, Lord, enough; and so she returned to her bed, and he following her, not knowing she had heard him, but when he was by her, she asked him, What he meant by saying, Enough, Lord, enough? he shewed himself dissatisfied with her curiosity, but told her, He had been wrestling with the Lord for Scotland, and found there was a sad time at hand, but that the Lord would be gracious to a remnant. This was about the time when bishops first overspread the land, and corrupted the church. This is more wonderful still, An honest minister, who was a parishioner of Mr. Welch many a day, said, "That one night as he watched in his garden very late, and some friends waiting upon him in his house, and wearying because of his long stay, one of them chanced to open a window toward the place where he walked, and saw clearly a strange light surround him, and heard him speak strange words about his spiritual joy." But though Mr. Welch had upon the account of his holiness, abilities and success, acquired among his subdued people, a very great respect, yet was he never in such admiration, as after the great plague which raged in Scotland in his time.
