Was It Designed?, page-1892

"28 Be on guard for yourselves and for all the flock that the Holy Spirit has appointed you to as overseers, to shepherd the church of God, which He purchased with His own blood."

With his own blood in the very context, if you gave up one of your children (Son) = they are deemed as your blood, blood of you.

So you spread the father of lies words when you falsely claim that God literally shed his own personal blood.
