I like the perspective of looking at it from God's perspective. What exactly is it that God wants us to become? Jesus tells us the following:
John 17:20-23
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.
22 And the glory which thou gavest me I have given them; that they may be one, even as we are one:
23 I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me.
It appears that the desire of Jesus is that we learn to become one with the Father and Jesus even as they are one with one another. How does faith play a role in becoming like the Father and Jesus?
