He has always been.  He will always be.  He walked among us.  He who walked among us ascended back to His Father.  From His Father, He poured out the Holy Spirit on us.  The Spirit has entered our lives to testify of Jesus, to guide us into Truth and to reshape us in the divine image,  He who ascended will come back for us. Meantime we live in His power and for His glory.

“I came from the Father and entered the world; now I am leaving the world and going back to the Father.” John 16:28 (NIV)
