**Tackiling the sin part**

Highlighting a false premise, that one must experience something for one to know/understand it. It is worth noting that experience is a type of knowledge ...

This is actually quite a loaded question philosophically, theologically, etc. Theologically, there is always *mystery*.

Beginning here we see the reason. The mistake is to view sin as *something*, while it is actually **an absence of something.** cf. [Evil | New Advent]( http://christianity.stackexchange.com/questions/31440/does-jesus-god-understand-uncertainty-or-sin).

Jesus, is God, therefore, ALL Goodness, ALL Truth, ALL, Love, etc. Hence St. Paul, *for he cannot deny himself.*

Not only did Jesus not sin, he could not sin (he was impeccable cf. [The Incarnation | New Advent](http://www.newadvent.org/cathen/07706b.htm)).

Herein is the mystery: Jesus, as Son, moves naturally and necessarily toward the Father, yet also freely.

Sin understood here as doing one's will in opposition to God's.
