That is a term that the apostle Paul used of himself. I dare say that the majority of those who have genuinely experienced God’s salvation would be willing to argue with Paul on that count. I know I would.
Jesus came into the world to save sinners. That my perfectly Holy King would die for me is something that amazes me almost every day. A lying, corrupt, self-centred, hypocrite. A man who has hurt uncounted people. A man who is dishonest to the core. Mean, unloving, perhaps unable to love. While unlike Paul I have not literally killed anyone, it is only by accident.
And yet here I am. I'm loved by the greatest Love in the universe.
Altogether undeserving, Jesus treats me as though I deserve His love.
Altogether unworthy, Jesus loves me as though I was the most godly man on the planet.
How can a person not be blown away by Grace and Mercy and Love shown to such a sinner as me?
If you allow Him, Jesus will do the same for you.
“Amazing love, how can it be?
That you my King would die for me.”
