When Jesus had received the sour wine, he said, “It is finished,” and he bowed his head and gave up his spirit. — John 19:30
This declaration is translated from the Greek word teleō, meaning to pay a debt. Through sin (our wrongs), all of humanity incurred a debt that we could have NEVER paid by our own means. After all, how can the sinful remove their own sin? Who was without sin that could remove our sin and guilt? Because God is infinitely just, sin must be eradicated — it cannot coexist (in fellowship) with Him.
And thus, through Jesus’s pure and sinless life, He atoned for, made amends, undid our wrong, and removed the sin/guilt stain on humanity. The sinless Jesus took on our sins, through His death on the cross, so that we could now be sin-less!
Knowing His purpose had been fulfilled, Jesus was ready to finish His assignment (paying His life for our sins) and return to His Father. Jesus has already secured the greatest victory in any battle that we will face in our lifetime. We’ve already won. Because He finished His assignment, you can now finish yours!
