To compel the unsaved to salvation, the backsliders to return unto Jesus Christ, and accept him-with assurity-as Lord and Savior, over their lives, according to the scriptures.
Romans 10:9-10
"That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation."
