Forgiving Sins on Earth

I was just thinking about the idea of Jesus forgiving sins on earth, and the nature of sin, in combination with the verse(s) "you are gods."

Reference: Matthew 9:1-8

So sin could likely be seen as a disagreement, a dissonance, between two entities, specifically taught as between man and God. This creates a rift between the realities that each party occupies, that "separation from God" effect. Jesus indicating/demonstrating that he has the power to forgive sins on earth is quite important, as it closes this gap between man and God, but when combined with the idea that each of us has this own individual realm we are sovereign over (perhaps what is meant to be illustrated by the "you are gods" psalm verse and subsequent quote by Jesus (John 10:34)), it indicates a complexity and applicability to the idea of sin. Sin could be viewed as a rift between two individuals in the same way as it is seen as being between man and God. This rift would be between the two individual realms that each is sovereign over. 

Now, with this definition in mind, Jesus did indicate that the Son of Man has the power to forgive sins on earth, it could be concluded that this claim includes such person to person trespasses, not just those between man and God (God being sovereign here). This seems like a different ability altogether, but would be covered under the phrasing in the claim made, as long as each party involved was on Earth at the time. While in the case of God it would be a kind of direct agency, a permission to forgive on God's behalf that was granted in advance, when it comes to forgiving sins (closing rifts) between individuals, it seems like it would need to operate differently if free will were to be preserved in the process. Honestly this process between individuals feels like an even more difficult thing to do, considering all the various personalities that might be involved in this process, than forgiving sins against God would be.  It's interesting because we see from that section a scaling of difficulty is already demonstrated in that forgiving sins against God is more difficult to fathom/grasp than telling a lame man to walk, and this idea of certainly being able to forgive sins between individuals feels more difficult to guarantee in the same way than forgiving sins against God.

It could be that sin is only with God, but why use a different term for the same basic concept involving others who are also called gods? The mechanism of a dispute being resolved between two different realm sovereigns seems to be the same, I think the perspective is difficult to see now because we have been created in a realm where God is sovereign and so it feels materially different, but I think that was part of what Jesus was trying to demonstrate subtly is that it is a matter of location and perspective, but he had the key to doing each (reconciling man and God and reconciling one to another) here on Earth. There are still some question marks in this line of thinking for me, but it feels correct or at least like a good start toward a new revelation in reality crafting, and I wanted to get it down before it slipped my mind as things rarely slip back into my mind once they've slipped out, these days.
