My favorite chapter is John 17.
In the beginning Jesus prays for His disciples, but then later He prays for US.
John 17:20 Neither pray I for these alone, but for them also which shall believe on me through their word;
21 That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.
When one receives the Holy Ghost, you receive all three parts of God as they three are one God.
