He will speak on the links between art and spirituality in a sermon at Crathie Kirk, the church the Queen and royal family attend while in residence at Balmoral.
The painter, known for his expressionist Scottish landscapes, is trained as a Lay Reader in the Church of Scotland and frequently preaches at churches in Argyll.
He is the first of a group of invited speakers to give a sermon at the church while the royal family is at Balmoral this summer.
He said: "I am extremely honoured to accept this invitation. I enjoy every opportunity to preach, and every congregation is different, but this engagement is a little bit special.
"My theme will be art, creativity and spirituality, a subject close to my heart."
Minister for Crathie and Braemar parsish, Rev Kenneth MacKenzie, said: "It's been a practice since Victorian times of having guest preachers during the time that certain members of the royal family are here.
"It's always a privilege to be around here at this time. Guest preachers are always hugely anticipated."
