I think that this Matryoshka doll can help us to understand a prayer that Jesus prayed for his followers. On the night he was betrayed, Jesus prayed "for all of those who would put their trust in him." In his prayer, Jesus said, "Father, I pray that they all may be one as you and I are one. Just as you are in me and I am in you, may they also be in us." Jesus wanted all of his followers to be one.
That they all may be one; as you, Father, are in me, and I in you, that they also may be one in us: that the world may believe that you have sent me.
