What Adam Lacked from Tony Reinke @ Miscellanies
"But this condition represents something big because it points to the one thing Adam could not possess in the Garden of Eden—certainty....
How can this be? How can a sinless man live with temporal uncertainty and a sinful man live with eternal certainty? Simple. Christ is our obedience. It was our uncertainty that was put to the test in the wilderness temptations, it was our certainty on the line when Christ was tempted in every way throughout his 33 year life. It was at every moment, in every thought, deed, and desire that our certainty was tested. Christ was without sin. He was the perfect Savior! And He could say the words that Adam never could—It is finished.
And because we are united to Christ, because he lived without sin, because he lived a life under the law to perfection, he becomes our certainty. The perfect life and death of Christ represents the completion of a perfect life—no sinful actions, no sinful thoughts, no sinful decisions. Once complete, a life of perfection brings with it perfect certainty.
Whatever spectacular dreams we entertain of Eden—and it certainly was a paradise beyond anything we can experience in this life—we possess in the gospel something foreign to Adam’s pre-fall experience. May we thank our Savior for this precious gift of eternal assurance, the one thing even a sinless and perfect garden could not promise."
