On February 15, 1928, he was elected to the highest office and given the highest rank attainable in Freemasonry, that of Most Grand Master of a sovereign Masonic Grand Jurisdiction.

His greatest work was the organization of the Order of the Rainbow for Girls. This is a junior organization for girls of the teen age from Masonic, Eastern Star, and Amaranth homes, and the friends of members of Rainbow. One evening in the spring of 1922, Mr. Sexson had been asked to make an address before South McAlester Chapter No. 149. As the DeMolay had come under his close study and observation during his Masonic activities, he became more and more conscious of the fact that an Order for girls setting forth some if the truths of Masonry would be necessary. He made a stirring appeal for such an organization in his address and the Worthy Matron, Mrs. Sarah Church, immediately replied, "We would start it if we had someone to write the ceremony of Initiation."Mr. Sexson said, "I will write the Ritual." The next day, he wrote the Ritual, giving it the name "Order of the Rainbow for Girls." He dictated it to the Church stenographer, Mrs. Helen Ambrose, in the study of the First Christian Church of which he was then a minister. He asked the regular officers of South McAlester McAlester Chapter No. 149, O.E.S., to exemplify the work and furnished them with typewritten copies of the Ritual.

On April 6, 1922, the degree were exemplified for the first time on a class of one hundred seventy-one girls in the auditorium of the Scottish Rite Temple, McAlester, Oklahoma. The Supreme of governing Body was formed by Mr. Sexson in June, 1922. He wrote the law governing the Supreme Body was well as the law governing the Subordinate Assemblies. At the formation of this Supreme Body, Mr. Sexson was made the Supreme Recorder and later was given the title, Supreme Worthy Advisor Emeritus.

On December 20, 1953, Mr. Sexson died in a McAlester hospital, following a short illness. The funeral service was held at the First Christian Church where he served as minister for many years and where the Ritual of the Order of the Rainbow for Girls was written.
