This question was asked by Pharaoh in Ex 5:5 in which also he goes on to state I do not know the Lord, nor will I let Israel go.
This same question and reaction exists in the world today. Often times people react in the same why Pharaoh did when they are told to do something God expects of them because they haven’t taken the time to figure our who he is. Because they are not familiar with Him they cannot appreciate or feel the need to obey Him much the same way Pharaoh chose not to listen to Moses and Aaron.
The answer to the question of who the Lord is can be found in multiple passages of scripture. I would like to simply focus on one that Paul makes reference to in Act 17:22-32 which is listed below.
22 Then Paul stood in the midst of the Areopagus and said, “Men of Athens, I perceive that in all things you are very religious; 23 for as I was passing through and considering the objects of your worship, I even found an altar with this inscription:
TO THE UNKNOWN GOD.
Therefore, the One whom you worship without knowing, Him I proclaim to you: 24 “God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. 25 Nor is He worshiped with men’s hands, as though He needed anything, since He gives to all life, breath, and all things. 26 And He has made from one blood[c] every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, 27 so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; 28 for in Him we live and move and have our being, as also some of your own poets have said, ‘For we are also His offspring.’ 29 Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising. 30 Truly, these times of ignorance God overlooked, but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”
Christians today have the same responsibility Paul had to teach who God is to those in the world. Ignorance of who God is will not be an acceptable excuse for refusal to follow His commands. It is the Christians’ responsibility to proclaim God to this world and help people to understand who He is so they will not question why they should obey Him.
The question I would ask you today is do you know who God is and why you must obey Him? If not, the time to learn is now and they way to do so is search His Holy Bible. If you do know God and why He must be obeyed, are you obeying Him by sharing the Gospel with others. If not you need to start today. Part of knowing who God is involves doing what He expects of you and what he expects of you is spreading the Gospel.
May we all live everyday serving God and helping others come to know and obey Him.
