Exodus 4v18-31

Moses heads back to Egypt after 40 years. The LORD tells him Pharaoh isn't going to listen. In fact the LORD is going to harden Pharaoh's heart. We shouldn't think "Poor Pharaoh". He had hardened his own heart against God despite the amazing backstory of the Israelite people. And despite the fact that all the while he kept trying to crush them, they kept growing. We are told to not harden our hearts when we hear God's voice. Saving God's people is costly. The One speaking to Moses - the Son of God - would die. And he is the Bridegroom of blood - he laid down his life for his bride, the church.
