God has spoken to us in that He raised Jesus from the dead.

The key to totally understanding this passage is to understand that God's word always accomplishes what God desires (Isaiah 55:11). God's word went out from His mouth and Jesus received that word in the Spirit at the Jordan and he obeyed that word, the will of God. The Father's word was his food, his bread for life (Jn 4:34; 6:57; 12:49-50), the food of this man of flesh. Because he ate this bread, God's word, by doing it, this word, his bread became flesh. That is what happens when you eat bread; it becomes you, your flesh. Because the word became flesh, that flesh is the word of God and the word of God will accomplish what God had commanded his word to accomplish. That dead body was His word and God had commanded His word to raise this flesh to life and return to him full of grace and truth (see Isaiah 55:11 again). For this reason, death could not hold Jesus. He had fully obeyed the will of God and become that word of God, "It is finished." And God the Father's word always accomplishes what he desires even if his word is a dead body of flesh.

God has spoken to us in that he raised Jesus from the dead.

Destroying God the Father's Temple was a very bad idea and the Father let them know it. "If any man destroys the temple of God, God will destroy him." 1 Corinthians 3:17. Refer to AD 70

"I will put MY WORDS in his mouth"
Deuteronomy 18:18

What sign do you show us? John 2:18
Signs which God did Acts 2:22

A dead body of flesh was in the tomb. It had accomplished all that God had sent it to do - the word had become flesh. "So will My word be which goes forth from My mouth. It will not return to Me empty, without accomplishing what I desire, and without succeeding in the matter for which I sent it."
Isaiah 55:11.

God sent his word upon Jesus at the Jordan; Jesus obeyed the will of God, this word, his bread, and the word became flesh. God's word which He sent out did not return to him void but full of grace, truth, and power.
