Ascension of Christ
The Ascension of Christ is His glorification.
"After the Lord Jesus had spoken to them, he was taken up into heaven and He sat at the right hand of God" Mark 16:19.

His ascension meant that He would send the Holy Spirit to dwell in believers, taking the place of His bodily presence, and continuing what He had done while here (John 14:16-17; 16:5-7). "All this I have spoken while still with you. But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you" (John 14:25-26). And, "He will bring glory to me by taking from what is mine and making it known to you" (John 16:14) 
Although the place of the Ascension is not distinctly stated, it would appear from the Acts that it was Mount Olivet.  The Feast of the Ascension, commemorating the Ascension of Christ into heaven, according to Mark 16:19, Luke 24:51, and Acts 1:2, take universal observance the fortieth day after Easter Sunday.
