Exodus 12

In this passage God gives the Israelites very specific instructions for the last plague in Egypt. This instruction was something to be remembered for all time and taught to their families for generations. With this part of God's lesson was complete. Obedience was so important in this. Good intention or substitutions wouldn't work in this case. We have to be aware of this in many of commands from God for us as well. Obedience is great gain. Disobedience leads to death. We should take our obedience seriously.
