'Insight' in the Bible
For this reason, since the day we heard about it, we have not stopped praying for you, asking [specifically] that you may be filled with the knowledge of His will in all spiritual wisdom [with insight into His purposes], and in understanding [of spiritual things],
so that you will walk in a manner worthy of the Lord [displaying admirable character, moral courage, and personal integrity], to [fully] please Him in all things, bearing fruit in every good work and steadily growing in the knowledge of God [with deeper faith, clearer insight and fervent love for His precepts];
We proclaim Him, warning and instructing everyone in all wisdom [that is, with comprehensive insight into the word and purposes of God], so that we may present every person complete in Christ [mature, fully trained, and perfect in Him—the Anointed].
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 whom are hidden all the treasures of wisdom and knowledge [regarding the word and purposes of God].
Let the [spoken] word of Christ have its home within you [dwelling in your heart and mind—permeating every aspect of your being] as you teach [spiritual things] and admonish and train one another with all wisdom, singing psalms and hymns and spiritual songs with thankfulness in your hearts to God.
