There's a man-centered “gospel” that says that Jesus died because you were so valuable. He saw the "gold" underneath your sin and was motivated by your worth or value to save you. Another way that this is said is, "The cross isn't a revelation of your sin, but a revealing of your value." Some even explicitly teach that the infinite value of the blood of Jesus is equal to the value of your life (God wouldn’t pay an infinite price, if your life wasn’t in equality with His blood).
But what does Scripture say? Let's look at the example of why God chose to save Israel in the book of Deuteronomy:
"It was not because you were more in number than any other people that the Lord set his love on you and chose you, for you were the fewest of all peoples, but it is because the Lord loves you and is keeping the oath that he swore to your fathers, that the Lord has brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.”- Deuteronomy 7:7-8
God didn't choose to save Israel because they were more valuable or greater in number than other nations (they were the fewest of all peoples). His motivation for saving Israel was based in His love, not their value, greatness, or worth. In Ezekiel chapter 16, God even tells Israel that their sins are worse than Sodom and Samaria’s sins, and yet God chose to be merciful to Israel (and give the others justice) because of His covenant love:
“As I live, declares the Lord God, your sister Sodom and her daughters have not done as you and your daughters have done.” - Ezekiel 16:48
“Samaria has not committed half your sins. You have committed more abominations than they, and have made your sisters appear righteous by all the abominations that you have committed.” - Ezekiel 16:51
“Yet I will remember my covenant with you in the days of your youth, and I will establish for you an everlasting covenant. Then you will remember your ways and be ashamed when you take your sisters, both your elder and your younger, and I give them to you as daughters, but not on account of the covenant with you. I will establish my covenant with you, and you shall know that I am the Lord, that you may remember and be confounded, and never open your mouth again because of your shame, when I atone for you for all that you have done, declares the Lord God.”
The same truth applies to our salvation. Christ died for us while we were ungodly sinners-- His enemies:
“For while we were still weak, at the right time Christ died for the ungodly. For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die—but God shows his love for us in that while we were still sinners, Christ died for us.”- Romans 5:6-8
“For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life.” - Romans 5:10
When we begin to think that we are "worthy," then God's grace is nullified, and man's glory is central. But when we realize that we are unworthy and unlovable, but God sets His love upon us in spite of our sin (an infinite debt), then God's love and grace looks more glorious.
"But aren't we valuable because we are made in God's image?" Yes, we have created value because God created us in His image (Gen. 1:26). But that image was marred by sin in the Fall, and has left all mankind guilty, worthy of God’s wrath, or justice in hell:
“None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one.”
Our created value does not play into the motivation or reason that God chose to be compassionate and gracious toward sinners. He chose to love and save sinners because He is love. The reason our salvation required the infinite value of the blood of Jesus is because our sin is an offense against an infinitely holy God, which means we owe an infinite debt that we cannot afford to pay.
We are valuable because God loves us. God doesn't love us because we are valuable. One message appeals to our pride and focuses our attention on our own greatness, while the other humbles us as we focus on the depth of God's amazing love for unworthy sinners, who He adopts as sons and daughters!
