And He Himself is the propitiation for our sins, and not for ours only but also for the whole world. 1 John 2:2
We understand that God knows the future, that nothing surprises Him or is outside His sovereign control.
Adam’s sin didn’t catch God off guard or force Him to Plan B …
God knew man would fall, that he would need salvation and that God would have to accomplish it Himself.

The blood. The suffering. The death.
And He willingly chose to pay that price.
