The reason my Father loves me is that I lay down my life—only to take it up again. No one takes it from me, but I lay it down of my own accord. John 10:17-18 (NIV)
Indeed, out of love for his Father and for men, whom the Father wants to save, Jesus freely accepted his Passion and death. Catechism of the Catholic Church.
Before he was given up to death, a death he freely accepted, Eucharistic Prayer II, English translation of The Roman Missal.
Freely You gave it all for us. Surrendered Your life upon that cross. This is our God, by Reuben Morgan. Hillsong.
Jesus freely gave His life for all of us.

The OT sacrifies in themselves were not enough. A point I discovered last week, and want to read more about.
