When Melvine and I were at Asbury Theological Seminary from 1960 to 1963, we were privileged to participate in an annual Missionary Convention at the Wilmore United Methodist Church when the Rev. Dr. David Seamands was the senior pastor. To add to my knowledge his brother Dr. J. T. Seamands taught World Missions in our seminary and I took a few courses from him. One of them was on how to prepare for a successful missionary convention.
I began the Missionary Convention concept in my first church in Alabama at the Brownville Pentecostal Holiness Church. I believe it was the first such convention in our denomination.
One of the most important things any pastor can do it to follow the Great Commission.
Jesus came to them and said, "All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age."
