Question: Why would God sacrifice his Son to save me?

Why is my life so important that God would give the life of his only Son to save me?

Do you want the nice answer or the snarky but kinda true one?

Begin Snarky Answer

Why would God sacrifice his Son to save you? Actually, he didn’t.
Let me explain.
There is an inaccurate and only partially dangerous myth that floats around in Christian circles regarding how much God loves people and the motivation behind the death of Christ. The myth goes like this:

God Loves you so much that if you were the only person on the face of the Earth, he would still have sent his Son to die for you!

Now that’s a nice sentiment and all, but it is wrong in at least two ways:

1. You are not the only person on the face of the Earth.
2. The Bible never tells us that Christ died for one isolated individual.

Now, I’m not being all that snarky, because this is really important for understanding the teaching of the Bible.
God didn’t just create one person. He created TWO people. What’s more, he created those two people with a command that they make babies and lots of them. In fact, he created them to “fill the earth” with more people.
Here’s an important point. God didn’t want one person to bear his image. He wanted an entire planet full of image-bearers! He wanted a family. That’s why it was so devastating that the first two humans turned their backs on God. Because of them, the entire family was doomed to bear the burden of sin. God didn’t need to redeem just a few individuals. He had to do something to redeem the entire family, and his method for doing so was to initiate a brand new spiritual family through the line of Seth, Noah, Abraham, David, and finally Jesus.
There are a number of biblical references that emphasize this.
First of all, God is called Father throughout the New Testament which reaffirms that God is all about the creation of a family.
Secondly, the famous passages on God’s love as the motivator for Christ’s death are all passages that talk about the salvation of a collective and not just isolated individuals. Here are two examples:

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. — John 3:16 NIV

But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. — Romans 5:8 NIV

And finally, the teaching of the New Testament is clear that Jesus came to redeem for the Father a people and not just individuals.

For he chose us in him before the creation of the world to be holy and blameless in his sight. In love he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will — Ephesians 1:4-5 NIV

For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, and in one body to reconcile both of them to God through the cross, by which he put to death their hostility. He came and preached peace to you who were far away and peace to those who were near. For through him we both have access to the Father by one Spirit. — Ephesians 2:14-18 NIV

We are easily tempted to be individualistic, and the claim that God loved each one of us so much that he would have sent Jesus to die even if it were only for that one person is a little inaccurate. The point of the Bible is clear. God wants a family, and so he did everything he did to build for himself a family.
The Bible has no room for individualistic Christianity.

End Snarky Answer

Okay, here’s the answer the original questioner was looking for.
Your life is not so important that God would sacrifice Jesus to save you, but as a matter of fact, your individual life is an eternal treasure worth so much more than you can imagine. In fact, your individual life is actually worth so much in God’s eyes that he would ask his Son to endure temporary pain to bring you fully into his eternal family.
Jesus endured temporary pain to bring you into an eternal family.
