Not sure of your exact wording but it reminds me of Christ speaking in John 10:15
Just as the Father knows me and I know the Father--and I lay down my life for the sheep. NIV translation.
And further in John 10:18 Christ says:
"No one takes it from me, but I lay it down of my own accord. I have authority to lay it down and authority to take it up again. This command I received from my Father.”
