The most likely author of the book of Mark is John Mark, who was a companion of both the apostle Paul and Peter. According to church tradition, Mark wrote his gospel based on the teachings of Peter, making it a firsthand account of Jesus’ life and ministry.

From an evangelical Christian perspective, Mark 9:35 contains a significant teaching of Jesus where he says, “If anyone wants to be first, he must be the very last, and the servant of all.” This statement reflects the humility and servant-heartedness that Jesus taught his disciples, challenging them to embrace selflessness and prioritize the needs of others above their own ambitions. This verse serves as a powerful reminder for believers to adopt a servant attitude and follow the example of Jesus in serving others.
