The LORD God told Moses and Aaron how His actions would be rejected by Pharaoh king of Egypt.  “…he will not listen to you…”  even though God’s many miracles against the Egyptians would be experienced by them.  Exodus 7:3-4
The Pharaoh did not believe God.

God revealed that Pharaoh’s “no” to letting the sons of Israel go to worship Him would not stop God from taking the Israelites out of Egypt.

God also was telling the Egyptians, “know that I am the LORD.”

The LORD God reveals to me what I need to do – do I believe Him and His word?
If I believe the living God of the Holy Bible – I will do what He says to do.

 10 “For with the heart one believes and is justified, and with the mouth one confesses and is saved.”
(ESV)Romans 10:10

I am working on at least one of the following commands of God:
Ephesians 4:25 Don’t lie – speak truthfully.

Ephesians 4:26 When angry – forgive before the sun goes down

Ephesians 4:27 Do not let the devil have a foothold in my life

Ephesians 4:28 Quit stealing but do something useful, go forward and help others

Ephesians 4:29 Do not let unwholesome words be spoken by my lips
Do speak words of encouragement to build others up in a good way – and don’t use flattery!

~ Take it to heart ~

What does God know about me?  God knew Pharaoh would not believe or let the sons of Israel go… even after much pressure of the judgment of miracles.

God shows and reveals, what He expects of me – do I believe Him or do I ignore Him and say – ‘tomorrow I will do what He says?’
