20 Which[hos] he wrought[energeo] in[en] Christ,[Christos] when he raised[egeiro] him
[autos] from[ek] the dead,[nekros] and[kai] set[kathizo] him at[en] his own[autos] right hand[dexios] in[en] the heavenly[epouranios] places, KJV-Interlinear
20 which He
brought about in Christ, when He raised Him from the dead, and seated Him at
His right hand in the heavenly places, NASB
Wrought, 'energeo,' means to be active, operative, effective, effectual, efficient, to accomplish.
And God accomplished salvation and the pinnacle of His divine plan, at the Cross, when, by bringing all of history to that exact and precise day and point in history, on the very feast celebration which was dated from the time of Moses some 1500 years earlier, on the very afternoon on that feast day.
Jesus went into the grave and returned back from the grave with not only full life, but resurrected life.
The Bible teaches us that the creation of the universe was but finger work, while the work of salvation was arm work, requiring much greater effort to accomplish. And yet, God did so despite many thousands of years, despite many generations of humanity, despite many diseases, and wars, and famines and natural disasters, and so forth, even through periods of phenomenal unbelief, especially in the time of Jesus first advent.
All was accomplished with tremendous ease, as far as God is concerned, but with miraculous power and coordination in history as far as humanity is concerned.
No one, and nothing could have accomplished such a great and detailed and vast plan, except God and God alone.
And not only that, but Jesus was promoted out from death (as far away from God as one can possibly be), to the right hand position from the Father and given all of the power and sovereignty over all that exists, in a formal fashion, despite all of evils efforts to block that accomplishment.
And not only that, but every believer in Christ is in union with Him and shares in that same position of highest honor. And we are but dust.
That is something that you cannot obtain anywhere in this world, even if you lived a thousand lifetimes.
