Since Islam means submitting to God's will, Jesus was teaching his followers to become Muslims by saying they must do the will of God.

In the Gospel of Mark, Jesus emphasizes that those who do the will of God are his true family. However, this statement is not an endorsement of Islam but rather a call to recognize his unique relationship with God as His Son. The transfiguration event further illustrates this point, where God the Father commands the disciples to listen to Jesus, affirming his divine authority. This moment reveals Jesus' glory and confirms his identity as the fulfillment of the prophetic writings, distinguishing him from mere prophets or messengers. Therefore, the will of God encompasses recognizing and following Jesus, who is the beloved Son, rather than merely submitting to a set of rules or teachings that Islam might suggest.
