How do we know the call to ministry is legitimate?

The legitimacy of a call to ministry is rooted in both the command and the promise of Christ, as seen in Mark 1:17. Jesus calls His disciples to follow Him, assuring them that He will make them fishers of men. This dual aspect—a direct command from the Lord and a promise of transformation—affirms the ministry's validity. Furthermore, the understanding that such calls are not limited to the apostles but extend to all believers reinforces their authenticity, as all followers of Christ are called to bear witness to Him.
