This episode details Jesus' expectations and ideals for us--it's what we strive for as believers in Jesus Christ. Jesus even discusses perfection--which is always something we want and for which we reach. Another great Christian, the Apostle Paul, put it like this:
Philippians 3:12-14: "Not that I have already attained, or am already perfected; but I press on, that I may lay hold of that for which Christ Jesus has also laid hold of me. Brethren (& sisters), I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus."
