There have been mysteries shown throughout many generations where some know and see things others do not. Jesus explained this very well that a calloused heart with ears that are dull of hearing and eyes that are closed will miss out on His life saving message. He goes on to say though one should understand with their heart and their eyes and ears be opened unto His way will they be converted and healed! (Matthew 13:11-17). 11 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.12 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.13 Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.14 And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:15 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.16 But blessed are your eyes, for they see: and your ears, for they hear.17 For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.
It is the will of God to gather together all things in Christ, that which is in heaven and earth alike under the direction of His counsel, This mystery of His will when we as believers know and understand His gospel of the salvation of man allows us to be sealed with the holy spirit of promise(Ephesians 1:9-14). 9 Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:11 In whom also we have obtained an inheritance, being predestinated according to the purpose of him who worketh all things after the counsel of his own will:12 That we should be to the praise of his glory, who first trusted in Christ.13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
