## Catholic Perspective **Tackling 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 ... <hr></hr> This is actually quite a loaded question philosophically, theologically, etc. Theologically, there is always *mystery*. > [2 Timothy 2:13 > (RSVCE)](https://www.biblegateway.com/passage/?search=2+Timothy+2%3A13&version=RSVCE) > > 13 if we are faithless, he remains faithful— > for he cannot deny himself. 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://www.newadvent.org/cathen/05649a.htm). 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. <hr></hr> **Note:** Sin understood here as doing one's will in opposition to God's. <hr></hr> **[The] Uncertainty part** The Church teaches that Jesus had a three-fold knowledge: [acquired, infused, and beatific](http://www.newadvent.org/cathen/08675a.htm). Delving into this would answer if *Jesus was ever uncertain*; too broad a topic to be incorporated in this answer.
