Nothing can reveal what is in our hearts more than the holy spirit of God, for the spirit searches all things (1 Corinthians 2:9-12). 9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.10 But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
The infinite knowledge of God is not reserved only for the aged, but has the ability to be revealed unto babes by the Son of God Himself through the spirit!(Matthew 11:25-30), 25 At that time Jesus answered and said, I thank thee, O Father, Lord of heaven and earth, because thou hast hid these things from the wise and prudent, and hast revealed them unto babes.26 Even so, Father: for so it seemed good in thy sight.27 All things are delivered unto me of my Father: and no man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son, and he to whomsoever the Son will reveal him.28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls.30 For my yoke is easy, and my burden is light.

O Lord, our Lord, how excellent is thy name in all the earth! who hast set thy glory above the heavens.2 Out of the mouth of babes and sucklings hast thou ordained strength because of thine enemies, that thou mightest still the enemy and the avenger.
Paul expressed that it is by the spirit are the mysteries of Christ revealed! A knowledge which allows a gentile can be a fellow-heir of Gods promises when the gospel is believed and accepted (Ephesians 3:1-9). For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,2 If ye have heard of the dispensation of the grace of God which is given me to you-ward:3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words,4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)5 Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;6 That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel:7 Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.8 Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ;9 And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:
