Was Christ sitting next to the Father on His throne while He was on that cross?
1 John 3:16 This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers and sisters.
Laid, past tense.
Hebrews 10:10 And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
Once, not on and on.
Jebrews 9:28 so Christ also, having been offered once to bear the sins of many, will appear a second time, without sin, to those who are eagerly waiting for him for salvation.
Offered once, not offered over and over and over again.
No Jebrews to be found in my copy.
Evidentially you are confusing yourself with God
You mortal - God eternal
You subject to time and space - God timeless and infinte
You have a past and a future - God no past, no future only NOW
Methinks you do not understand that God exists outside of time and sace.
