Jesus didn't need faith.   We need faith.

Jesus is God.  What He thinks happens!  There is no imperfection or fissure between His will and His intellect or His body.  His will is supremely/infinitely powerful. 

He is action itself.  There is no gap or delay. 

The theological virtues of faith, hope and love are "helps" that God gives us in order to be closer to Him, to love Him as we should.   

We don't "generate" these ourselves...they are supernatural virtues...they are graces we ask for. 

Faith is needed in order to know God, love God, serve God as He wants us to know, love, and serve Him.   

Think of faith as what's needed to love God "beyond reason".  

Our intellect is puny and can only help us know, love, and serve God to some quite limited amount.   We need faith to "go beyond" reason, in order to love Him as we should. 

So Jesus was/is God, and so He didn't need faith or hope to do any of those things He did. 

We will not need faith or hope once we get to heaven.
