God's eternal plan was for God the Son to give his life to pay for the sins of humanity. Jesus's death on the cross reveals the intense love of the Son for the Father and of the Father for the Son.
The kind of love that comes from God is focused on having good things happen to others even when those good things do not happen to the one who loves. This kind of love cares for others, no matter what they do.
This is a mild way for Jesus to say he will die and then will become alive again. Alternate translation: "I allow myself to die in order that I may bring myself back to life" (See: [[rc://en/ta/man/translate/figs-euphemism]])
