I've been reading John 5. Here's Jesus speaking to the Jews in verse 20: "For the Father loves the Son and everything the Father does he shows him." I stopped, thinking that if the Father loves the Son, then how could he sacrifice him to save us? Does he love us more than he loves the Son? I realized that this is possible only if the Father and the Son are one. So we have the Lord God sacrificing himself for us, and it all made sense.
