"Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear." (Acts 2: 33)
When Jesus sat down, it was the signal to the world and all eternity that the Work of redemption was finished (John 19: 30).
We are also seated above the heavens in Christ (Ephesians 2: 6), and so if we want to release His Holy Spirit in our lives, we are called to stay seated in Him.
The problem for many believers, and why they do not see miracles in their lives, is that they do not sit and rest.
They are convinced, either by their own flesh or the Enemy, that if they do not get off their own thrones and "do something."
Yet any attempt on our own, in our own effort will cause us to fall from grace (Galatians 5: 4), and it is the grace of God which defines us and drives us (1 Corinthians 15: 10), and it is this same grace which defends and promotes us in the midst of the greatest adversity (2 Corinthians 12: 9-10)
The writer of Hebrews strictly instructs all of us to rest in His Promise (Acts 2: 28-33), the Holy Spirit:
"Let us therefore fear,
lest, a promise being left us of entering into his rest, any of you
should seem to come short of it." (Hebrews 4: 1)
"Let us labour therefore to enter into that rest, lest any man fall after the
same example of unbelief." (Hebrews 4: 11)
When we rest, we trust in Him, and this faith allows His Spirit to work in our lives, blessing us and quickening us to do all that He wills within us to do (Philippians 2: 12-13)
We are called to rest, with the full understanding that when we stop, He starts, when we died to our own efforts, that He works all things together for our good.
