We are likely familiar with the idea of Jesus being the head of the body.
15 He is the image of the invisible God, the firstborn over all creation. 16 For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. 17 And He is before all things, and in Him all things consist. 18 And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence. Colossians 1:15-18 (NKJV)
In the above passage it is clear that all things point to Jesus. Everything was created both by Him and for Him. This includes the visible and invisible. While we may recognize that the creatures in the spirit realm are part of the invisible, another aspect to consider is that the structure of relationships is part of the invisible realm Jesus created.
While not obvious or visible Jesus in fact created the ways we can relate to Him. Look at what He says. 15 No longer do I call you servants, for a servant does not know what his master is doing; but I have called you friends, for all things that I heard from My Father I have made known to you. John 15:15 (NKJV)
Here Jesus is speaking to the 11 (Judas has left to betray Him) and He identifies a change in His relationship to them. What is clear in the text is the relationship changed over time. I believe this is Jesus desire for all of us and it is not automatic, particularly given His warning in Matthew 7 that people could appear to follow Him but not really know Him (Matt. 7:21-23).
Jesus has built into the structure of relationships that when we seek Him and choose to spend time with Him we have the privilege of becoming His friend. I think if we could see in the spirit realm we would be able to see a change in us, we would know when we moved from servant to friend.
What would others see if they could look at us?
