And Pharaoh said, Who is the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go (Exodus 5:2). Pharaoh could not obey because he did not know “whom” he should obey! The Bible says, that the earth shall be filled with the knowledge of the glory of the LORD as the waters cover the sea (Habakkuk 2:14), but until that day comes, those who know the LORD God Almighty, need to be sharing about Him and His grace to those who don’t.

Obedience comes with knowledge. If one does not know who the LORD is, how will they obey him? Our responsibility is to make Him known and the responsibility of those who know him is to obey Him.

Exodus 5:2 (KJV)
2 And Pharaoh said, Who is the LORD, that I should obey his voice to let Israel go? I know not the LORD, neither will I let Israel go.
3 And they said, The God of the Hebrews hath met with us: let us go, we pray thee, three days’ journey into the desert, and sacrifice unto the LORD our God; lest he fall upon us with pestilence, or with the sword.
