Apostle Alex Mitala is a family man, church planter, bible teacher, educationalist, and community transformer based in Kampala, Uganda. He is married to Catherine Mitala and together, they have six children. Mitala is the founder of Back to the Bible Truth Evangelistic Mission (BBT) organization.

At the time of Mitala's conversion to Christianity, Ugandan Dictator Idi Amin was persecuting Christians, pressuring many to convert to Islam. Following the refusal of the nation's Balokole (Born-Again Christians) to deny Christianity or join mainline Christian churches, Amin responded by closing their churches and expelling missionaries throughout the country.

The persecution during that period led to the deaths and imprisonment of many of Mitala's associates, driving the church underground to conduct its services and operations in secret.

In 1974, Mitala joined the underground preaching movement to strengthen the hidden churches of Uganda. His activities later extended to smuggling Christian literature from Kenya, resulting in his arrest in 1978. Mitala was miraculously spared and freed shortly afterward, facing no charges.

Following Idi Amin's 1979 ouster, Mitala, who had stayed in Kenya, returned to Uganda to establish a ministry focused on church planting and evangelism, while concurrently pursuing a correspondence course at a Nairobi Bible school. That same year, Mitala established the Back to the Bible Truth Evangelistic Mission (BBT Mission).
