'Manifest' in the Bible

and the Life [an aspect of His being] was manifested, and we have seen [it as eyewitnesses] and testify and declare to you [the Life], the eternal Life who was [already existing] with the Father and was [actually] made visible to us [His followers]—

They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all 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.

The one who practices sin [separating himself from God, and offending Him by acts of disobedience, indifference, or rebellion] is of the devil [and takes his inner character and moral values from him, not God]; for the devil has sinned and violated God’s law from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.

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.

By this the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] into the world so that we might live through Him.
