For all that we see of Godliness is the Sefirot. However, the Sefirot are one way in which the Supreme WIll wanted to show His laws. This way is not intrinsic to Him but one that He willfully chose. If so, what we see of Godliness is not intrinsic Godliness in itself but only what He wants us to see.
In that case, it might seem that you could not legitimately call the Sefirot Godliness but that you could only say they point to and indicate Godliness in a way similar to the way a written name designates the bearer of that name. The letters making up the name have no intrinsic connection with the bearer of the name but simply refer to him through an agreed convention. While the letters designate the bearer of the name, they are not in themselves a part of him in such a way that we could say they possess some intrinsic quality belonging to him. Yet we have called the Sefirot Godliness. If so, it must be that this radiation contains something Godly.
