In whom are hid all the treasures of wisdom and knowledge. ( Colossians 2:3)
When the LORD's disciples asked HIM why HE taught in parables "He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath. Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Isaiah, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive: For this people's heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes, and hear with their ears, and should understand with their heart, and should be converted, and I should heal them. But blessed are your eyes, for they see: and your ears, for they hear." (Mat 13:11-16)
It is very obvious that it is impossible for any man to hear, see, or understand (i.e.; know) the mysteries of the kingdom of heaven unless GOD in HIS sovereign mercy should grant them the ability to do so. The scripture says that man, in his natural state, is "dead in trespasses and sins." and apart from being given spiritual life he shall perish in his ignorance. This has been true from the earliest days of men and is demonstrated in Adam's disobedience in the midst of a veritable paradise in which he was placed.
Not only is man in total spiritual darkness but he loves to have it that way. (see John 3:19) It is not that he does not like religion or even that he doesn't maintain some belief in a higher power, but as Paul says, "Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools" (Rom 1:21-22)
The sad fact is that the greatest malady that has come upon men is not that they do not know of GOD at all, but that they love their own way more and delight in their own philosophies and theories. All men, without exception, are born into this state and will continue on in it unless the privilege of hearing and seeing their folly and HIS utter glory and dominion "is given unto them". The LORD hardens the hearts of men in their darkness and HE hides the truth and glory of HIS SON's absolute reign from all but that remnant which HE has chosen and who are the recipients of HIS mercy and grace.
OF THE LOVE OF GOD
The three divine Persons in the Godhead mutually love each other; the Father loves the Son and the Spirit, the Son loves the Father and the Spirit, and the Spirit loves the Father and the Son. That the Father loves the Son, is more than once said, (John 3:35, 5:20) and the Son is sometimes called the well beloved and dear Son of God, (Matthew 3:17, 17:5; Col. 1:13) he was from all eternity as "one brought up with him"; and was loved by him before the foundation of the world; and that with a love of complacency and delight; as he must, since "he is the brightness of his glory, the express image of his person", and is of the same nature, and possessed of all the same perfections with him, (Prov. 8:30, 31; John 17:24; Heb. 1:3; Col. 2:9) yea, he loved him as his Servant, as the Mediator, in his state of humiliation, and obedience, and under all his sufferings, and on account of them; and even while he bore his wrath as the sinner's surety, he was the object of his love, as his Son, (Isa. 42:1; Matthew 3:17; John 10:17) and now he is at his right hand, in human nature, he looks upon him with delight, and is well pleased with his sacrifice, satisfaction, and righteousness. The Father loves the Spirit; being the very breath of him, from whence he has his name, and proceeding from him, and possessing the same nature and essence with him (Job 33:4; Ps. 33:6; John 15:26; 1 John 5:7). The Son loves the Father, of whom he is begotten, with whom he was brought up, in whose bosom he lay from all eternity, as his own and only begotten Son; and as man, the law of God was in his heart; the sum of which is to love the Lord God with all the heart and soul; and as Mediator he showed his love to him by an obedience to his commandment, even though that was to suffer death for his people (Ps. 40:8; John 14:31, 10:18; Phil. 2:8). The Son also loves the Spirit, since he proceeds from him, as from the Father, and is called the Spirit of the Son, (Gal. 4:6) and Christ often speaks of him with pleasure and delight, (Isa. 48:16, 61:1; John 14:16, 17, 26, 15:26, 16:7, 13). And the Spirit loves the Father and the Son, and sheds abroad the love of them both in the hearts of his people; he searches into the deep things of God, and reveals them to them; and takes of the things of Christ, and shows them unto them; and so is both the Comforter of them, and the Glorifier of him (1 Cor. 2:10-12; John 16:14).
