You see, at just the right time, when we were still powerless, Christ died for the ungodly.
Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die.
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.
Romans 5:6-8 NIV

I’d give my own life in exchange for the lives of my kids and grandkids.
Let’s hope I never have to prove it, but their feelings for me at the time would be of zero consideration.
I’ve no desire to be a martyr or to be so pretentious to prove my love, but the fact is, when you create a living, breathing human being the bond is inextricable.
So much so that you long to save it from harm and forces both within or without at any cost, including your own life.
Here we see a perfect Father sending a sinless Son as His own incarnation and with an end game of dying to Himself as payment made for us to live forgiven.
You know the story. It’s a painful but brilliant plan to demonstrate the depth of His love in a way we can all humanly comprehend.
And to seal the deal, all that’s required in turn is for us to evaluate the evidence and believe in His plan.
A complex example made for simple minds like us to understand.
It’s like a divine sign, date, and return enclosed deal that parents and grandparents uniquely understand and agree to in return for the title.
