At birth the doctor informed MacAlmon's parents that he would likely not live through his first month, due to cranial stenosis (a premature closure of the soft spot in his head). According to his mother, she was pacing the floor with him every day and praying, "Lord, if You let him live, I will give him to You for Your service." Not long thereafter her baby healed, which MacAlmon ascribes to his mother's cry for help. MacAlmon believes that he not only received the gift of life at that time but also a special anointing and gift of music.
At the age of three, MacAlmon's mother began sitting him on the piano bench to occupy him, while she looked after his brothers. Quickly he began to discover the notes of “Jesus Loves Me,” a song he had learned in Sunday school. A steady progression took place. By the time he was five, he played his first solo in church.
MacAlmon became the church pianist at the age of 11. Winning state and national talent awards in his denomination became a regular event during his teenage years.
In the summer of 1973 MacAlmon claims to have had an unusual visitation from God, after an evening service at a youth retreat. He recalls, "It was as if God's presence was sitting on me like a cloud. His presence was so heavy that I physically could not even lift my head. I just knelt and trembled while His Spirit dealt with me. I knew that He was placing His mantle of worship upon me. I have never been the same since that special August night.”
