“What Would Jesus Do” is not a correct motivation saying. Who of us knows what Jesus would do? By contrast, all of our actions should be performed, “in his name.” Therefore, the correct cause for ministry should be: “what would Jesus have me do” that I may perform “in his name.”
All that we engage in must be done for the sake of Christ. No matter what the service, task, or ministry we are called to, if it is not done for the sake of Christ then it runs of risk of being for the glory of self, and thereby not acceptable to God.
