Scottish scholar Donald Meek states that: "he was instrumental in forming what became the largest Baptist congregation in the Gaelic-speaking Highlands, but he was also at the forefront of itinerant evangelism throughout the area. His warm-hearted evangelical Calvinism found expression in powerful preaching, in Gaelic and/or English as appropriate...Peter Grant is best known to Highlanders and Islanders as the composer of many Gaelic hymns of evangelical experience which have remained popular to the present day."
