John 17:18–19 (NKJV) 
18 As You sent Me into the world, I also have sent them into the world. 19 And for their sakes I sanctify Myself, that they also may be sanctified by the truth. 

It is one thing to realize that we are in the world and that Jesus Christ prays that we not be taken out of the world. But it's another level of spiritual insight and depth to realize that Jesus Christ has sent us into the world, that He has sent us into the cauldron. We're not just here existing in the cauldron struggling to make our way through life for the benefit of ourselves; we have been SENT into the cauldron, into this world by Jesus Christ—AS Jesus Christ was also sent by the Father into the cauldron. So, it compels us to give some thought to the reason, purpose, objective, and outcome for which Jesus Christ was sent by the Father into the cauldron as an explanation and purpose for why we are in the cauldron.
