'Insight' in the Bible
For this reason we also, from the day we heard of it, have not ceased to pray and make [ special] request for you, [asking] that you may be filled with the full (deep and clear) knowledge of His will in all spiritual wisdom [ in comprehensive insight into the ways and purposes of God] and in understanding and discernment of spiritual things -- "
That you may walk (live and conduct yourselves) in a manner worthy of the Lord, fully pleasing to Him and desiring to please Him in all things, bearing fruit in every good work and steadily growing and increasing in and by the knowledge of God [with fuller, deeper, and clearer insight, acquaintance, and recognition].
Him we preach and proclaim, warning and admonishing everyone and instructing everyone in all wisdom ( comprehensive insight into the ways and purposes of God), that we may present every person mature (full-grown, fully initiated, complete, and perfect) in Christ (the Anointed One).
so that their hearts may be encouraged, united in love and into all the wealth of the full assurance of insight into the knowledge of the mystery of God, Christ,
In Him all the treasures of [divine] wisdom ( comprehensive insight into the ways and purposes of God) and [all the riches of spiritual] knowledge and enlightenment are stored up and lie hidden.
Let the word [spoken by] Christ (the Messiah) have its home [in your hearts and minds] and dwell in you in [all its] richness, as you teach and admonish and train one another in all insight and intelligence and wisdom [in spiritual things, and as you sing] psalms and hymns and spiritual songs, making melody to God with [His] grace in your hearts.
