"Now when He had spoken these things, while they watched, He was taken up,and a cloud received Him out of their sight.".....[nkjv]
Before His vicarious Death and Resurrection, Jesus had told Nicodemus...'No-one has ascended to Heaven but He who came down from Heaven, that is, the Son of Man who Is in Heaven'. This tells us of the Omnipresence of God , Being In Heaven and on earth at the same time...[ viz. Father, Son and Holy Spirit. ] .Could this not also be a prophesy concerning Christ's Ascension to Heaven ?... to be accomplished at a later date,?...as recorded here in Acts.1:9-11.
As we grow in our understanding of the Christian Faith, we realise that we are also positionally seated in Heaven with Jesus ...[if not experientially] right now !..and .to be sat infers that the work of redemption has been completed for all eternity ....nothing can be added to, or taken away from, this perfect work.[ Ephesians 2:6 / Hebrews 10:12,14 ].We must fully aquaint ourselves with the fact that Everything concerning Our Lord Jesus Christ was Prophesied and predicted In the Scriptures. God Is not mocked [Galatians 6:7] and we have a duty to study and become fully conversant with these truths...then we will receive our reward in due season. !
The Prophet Zechariah tells us ...Ch.14:4..."In that day His feet will stand on the Mount of Olives"...in perfect fulfillment of the angel's prediction in Acts 1:9ff. ...............You see, in order to make sense of the present ..we have to know about the past ....and be forewarned of the future ! ONLY in The Bible can we find the answers to do this !....Saints ...G-R-O-W !!! and then you will see great things happen in your lives...by The Power of The Holy Spirit and The Love of God.
May The Lord Bless you.
