This sermon emphasizes the importance of doing God's will and being part of His family by following His commands.

The speaker highlights the transformative power of love, prayer, and obedience in spreading the message of Jesus and impacting the world for good.

John Piper preaches on the significance of Jesus' words to his mother and the beloved disciple at the cross, emphasizing three reasons why this is a tremendous encouragement to our faith. Firstly, Jesus' care for his mother highlights his even greater love and provision for obedient disciples who hear and do the word of God. Secondly, Jesus' ability to provide for his own in his moment of weakness assures us of his present power and exaltation to meet all our needs. Lastly, Jesus' assignment of a new relationship between Mary and John illustrates the benefits of the church as the family of God, where needs are met and relationships are formed beyond biological ties.
