'Perceive' in the Bible
And this is how we may discern [ daily, by experience] that we are coming to know Him [to perceive, recognize, understand, and become better acquainted with Him]: if we keep (bear in mind, observe, practice) His teachings (precepts, commandments).
Whoever says, I know Him [I perceive, recognize, understand, and am acquainted with Him] but fails to keep and obey His commandments (teachings) is a liar, and the Truth [ of the Gospel] is not in him.
But he who keeps (treasures) His Word [who bears in mind His precepts, who observes His message in its entirety], truly in him has the love of and for God been perfected (completed, reached maturity). By this we may perceive (know, recognize, and be sure) that we are in Him:
But he who hates (detests, despises) his brother [ in Christ] is in darkness and walking (living) in the dark; he is straying and does not perceive or know where he is going, because the darkness has blinded his eyes.
I write to you not because you are ignorant and do not perceive and know the Truth, but because you do perceive and know it, and [know positively] that nothing false (no deception, no lie) is of the Truth.
If you know (perceive and are sure) that He [Christ] is [absolutely] righteous [conforming to the Father's will in purpose, thought, and action], you may also know (be sure) that everyone who does righteously [and is therefore in like manner conformed to the divine will] is born (begotten) of Him [ God].
Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
By this we shall come to know (perceive, recognize, and understand) that we are of the Truth, and can reassure (quiet, conciliate, and pacify) our hearts in His presence,
By this you may know (perceive and recognize) the Spirit of God: every spirit which acknowledges and confesses [the fact] that Jesus Christ (the Messiah) [actually] has become man and has come in the flesh is of God [has God for its source];
We are [children] of God. Whoever is learning to know God [progressively to perceive, recognize, and understand God by observation and experience, and to get an ever-clearer knowledge of Him] listens to us; and he who is not of God does not listen or pay attention to us. By this we know (recognize) the Spirit of Truth and the spirit of error.
Beloved, let us love one another, for love is (springs) from God; and he who loves [his fellowmen] is begotten (born) of God and is coming [progressively] to know and understand God [to perceive and recognize and get a better and clearer knowledge of Him].
By this we come to know (perceive, recognize, and understand) that we abide (live and remain) in Him and He in us: because He has given (imparted) to us of His [Holy] Spirit.
And we [have seen and] know [positively] that the Son of God has [actually] come to this world and has given us understanding and insight [progressively] to perceive (recognize) and come to know better and more clearly Him Who is true; and we are in Him Who is true -- "in His Son Jesus Christ (the Messiah). This [Man] is the true God and Life eternal.
