"Do not observe his sight/appearance/vision or his height, for I have rejected him; [it is] not as man sees. Man sees (looks) with the eye, YHWH sees (looks) with the leb"(Hb. - heart/mind/inner man.) ~ 1 Samuel 16:7
Proverbs 4:1 - HEAR, MY sons, the instruction of a father, and pay attention in order to gain and to know intelligent discernment, comprehension, and interpretation [of spiritual matters].
1 Corinthians 2:14-15 - But the natural, nonspiritual man does not accept or welcome or admit into his heart the gifts and teachings and revelations of the Spirit of God, for they are folly (meaningless nonsense) to him; and he is incapable of knowing them [of progressively recognizing, understanding, and becoming better acquainted with them] because they are spiritually discerned and estimated and appreciated.  But the spiritual man tries all things [he examines, investigates, inquires into, questions, and discerns all things], yet is himself to be put on trial and judged by no one [he can read the meaning of everything, but no one can properly discern or appraise or get an insight into him].
Colossians 1:9 - 9For 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-- 10That 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]. 11[We pray] that you may be invigorated and strengthened with all power according to the might of His glory, [to exercise] every kind of endurance and patience (perseverance and forbearance) with joy,
Shalom, Light & Love,
