'Knowledge' in the Bible

[I always pray] that the God of our Lord Jesus Christ, the Father of glory, may grant you a spirit of wisdom and of revelation [that gives you a deep and personal and intimate insight] into the true knowledge of Him [for we know the Father through the Son].

remember that at that time you were separated from Christ [excluded from any relationship with Him], alienated from the commonwealth of Israel, and strangers to the covenants of promise [with no share in the sacred Messianic promise and without knowledge of God’s agreements], having no hope [in His promise] and [living] in the world without God.

and [that you may come] to know [practically, through personal experience] the love of Christ which far surpasses [mere] knowledge [without experience], that you may be filled up [throughout your being] to all the fullness of God [so that you may have the richest experience of God’s presence in your lives, completely filled and flooded with God Himself].

until we all reach oneness in the faith and in the knowledge of the Son of God, [growing spiritually] to become a mature believer, reaching to the measure of the fullness of Christ [manifesting His spiritual completeness and exercising our spiritual gifts in unity].

for their [moral] understanding is darkened and their reasoning is clouded; [they are] alienated and self-banished from the life of God [with no share in it; this is] because of the [willful] ignorance and spiritual blindness that is [deep-seated] within them, because of the hardness and insensitivity of their heart.
