'Enlightened' in the Bible

I am telling you the truth as a Christian man--it is no falsehood, for my conscience enlightened, as it is, by the Holy Spirit adds its testimony to mine--

the eyes of your understanding being enlightened so that you may know what is the hope which His call to you inspires, what the wealth of the glory of His inheritance in God's people,

For it is impossible, in the case of those who have once for all been enlightened, and have tasted the sweetness of the heavenly gift, and have been made partakers of the Holy Spirit,

But continually recall to mind the days now past, when on being first enlightened you went through a great conflict and many sufferings.
