'Manifest' in the Bible

They went out from us, but they were not of us; for if they had been of us, they would have continued with us: but they went out , that they might be made manifest that they all are not of us.

Beloved, now are we children of God, and it is not yet made manifest what we shall be. We know that, if he shall be manifested, we shall be like him; for we shall see him even as he is.

In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
