“Then the Lord said “Let my people go, so that they may worship me.””
Exodus 9:1 NIV
This slavery started under this Pharaoh. I assume they knew about God and sacrifices and had a relationship with God sometime during theses 400 years.
God is methodical in His actions. I will accept the bumps along the road Lord and I will do my best to be your disciple during the hard and questionable time. Please do not allow me to be lead into temptation and question you actions but to stay strong in the fight.
