'Seen' in the Bible

so that you may prove yourselves to be blameless and guileless, innocent and uncontaminated, children of God without blemish in the midst of a [morally] crooked and [spiritually] perverted generation, among whom you are seen as bright lights [beacons shining out clearly] in the world [of darkness],

The things which you have learned and received and heard and seen in me, practice these things [in daily life], and the God [who is the source] of peace and well-being will be with you.
