"If I have told you earthly things and you do not believe, how will you believe if I tell you heavenly things? No one has ascended to Heaven but He who came down from Heaven, that is, the Son of Man who is in Heaven." - John 3:12-13
Time is where we live but we can walk in the Spirit where God lives while we live here in time. Jesus, while standing on earth said that He was in Heaven. He had a body to operate here in time (on earth) but was claiming to be in Heaven.
DUAL REAL CITIZENS
"But we are citizens of the state (commonwealth, homeland) which is in Heaven, and from it also we earnestly and patiently await [the coming of] the Lord Jesus Christ (the Messiah) [as] Savior..." - Philippians 3:20 AMP
Do you not yet know that we are dual realm citizens? We have been given a body to fulfill our purpose here on earth but our citizenship is in Heaven and through the Spirit we can access our homeland, here and now.
"Still have many things to say to you, but you cannot bear them now. However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come. He will glorify Me, for He will take of what is Mine and declare it to you. All things that the Father has are Mine. Therefore I said that He will take of Mine and declare it to you." - John 16:12-15
Jesus told His disciples that He was going away so that they too could access Heaven in this passage of Scripture. He was literally saying here, "You are going to have a direct access to Father through My name because of what I am about to do." He was now going to be the Door for us to access our Father!
He is saying that we are now stuck here in time and can now access the realm of eternity, or the eternal realm, because of our connection with Him.
He was saying that you can't understand now, but when He leaves He is going to send you someone like Him, who has access to the things in Heaven and He is going to come and live in you and tell you what is going on in Heaven and give you access to the thoughts of the Father! In other words, Heaven is coming to you!
The veil of time has come to an end for those who will come to Him and believe. God said that Adam would have to work by the sweat of his brow when sin entered, but Jesus paid the price and walked sinless for us all, shed His innocent Blood and then gave us back the keys here on earth to Heaven! Whatever we bind on earth shall now have already been bound in Heaven and whatever we loose here shall have already been loosed there!
UNDERSTANDING OUR AUTHORITY IN CHRIST
He has given us authority here, not to bring our own will but His will on earth and He told His disciples when they asked Him how to pray that they should pray: "Thy Kingdom come, thy will be done in earth, as it is in Heaven" - Matthew 6:10.
When you get into the eternal realm in worship—you enter His gates with thanksgiving and enter His courts with praise (see Psalm 100:4). That is how we now access that realm and that is why we must worship Him in spirit and in truth! It gives us access to the Father. In the Lord's prayer, the first thing Jesus told His disciples to pray was, "Our Father who art in Heaven hallowed be thy name" (Matthew 6:9). We must hallow His name! We must praise Him for all that He is!
