John indeed answered the call of God for his life written long before he was born, disciples of Jesus also answered the call of their purpose, Paul the apostle was sent to the gentiles Acts 13, Peter was to build the church of God, James sent to the twelve tribes of Israel that are scattered abroad. Today many Christians do not know their purpose, many leave their God given assignment for roles different from their callings. It should be our daily pray to understand the calling of God in our lives and function in line with our ordained calling for by this we won't struggle carrying out our divine assignment.
