To serve Jesus is to follow Jesus. To follow Jesus is to be with Jesus.
It is not possible to truly serve Jesus without also following Him. If our service consists only of isolated acts — even sacrificial isolated acts — without a commitment to also go where He goes; and to do as He directs; such service is deficient.
To be a true servant of Jesus is to voluntarily subordinate our will to the will of the One being served. This type of service cannot be rendered at a distance. It is intimate. It is persistent. – Luther
