John tells us that from the very beginning of Jesus' life on earth, he loved his family (John 13:1). Most of what is written about Jesus' life is about his and his Father's love for us. But at the cross we are given another of the rare glimpses into his interactions with his mother.
Jesus looks down from the cross and sees his mother surrounded by her friends and her sister. John (the one who wrote the book we are studying) is standing near by. He has been one of Jesus' closest friends. Mary has other sons, yet Jesus looks at his mother and his disciple John and says, "Woman behold your son." And to John, "Behold your mother" (John 19:25-27).
John took care of Jesus' mother from that day until she died.
We know that his brothers eventually believed who he was (Acts 1:14), yet Jesus leaves the care of his mother to his best friend.
If Jesus trusted John enough to take care of his mother, we know we can trust the accuracy of John's writing of what happened.
