Philippians 2:5-8 "Have this attitude in yourselves which was also in Christ Jesus, who, although He existed in the form of God, did not regard equality with God a thing to be grasped, but emptied Himself, taking the form of a bond-servant, and being made in the likeness of men. Being found in appearance as a man, He humbled Himself by becoming obedient to the point of death, even death on a cross."

We have a clear presentation here of the deity of Jesus.  We're told that Christ pre-existed in the form (NASB/ESV/NKJV) or the very nature (NIV) of God.  Jesus existed before (cf John 17:5) taking the form of a bond-servant, taking on humanity and humbling Himself was obedient to death on a cross.   Confirming that His death on the cross was the very reason He came in the likeness of men.  This passage conveys that He truly was without sin, and was that perfect lamb of God.
