Yeshua, the Great I AM, came into the world as the light of the world, but the world loved darkness rather than light. But if the gospel be hidden, it is hidden from them that are lost in whom the god of this world has blinded the minds of them which believe not, least the light of the glorious gospel of Yeshua who is the image of Yahweh should shine unto them. 
The simplicity of the gospel is accepted by faith.
