Hear, O Israel: The Lord our God, the Lord is one. That's one of the most important statements in the bible. Jesus quotes it as being part of the first and most important commandment. Now let's put the statement in some contextual perspective. The world worships multiple false gods, idols and demons none of which are God. So let's translate this a bit differently, The lord our God is the One God. The use of the number one is very specific but exactly how it's used is very profound.
God is THE ONE, an all encompassing being, all powerful all knowing ever constant and never changing and He alone is the only One that is this way. This is the one true God who called out Israel to be is people and through Israel came Himself in flesh to call whosoever will. Hear ye whoever may read, the Lord our God is The One God and He seeks to know you, surrender to Him and your life will be renewed.
