A thorn in the flesh

"And lest I should be exalted above measure by the abundance of the revelations, a thorn in the flesh was given to me, a messenger of Satan to buffet me, lest I be exalted above measure." 2 Corinthians 12.7

The Work of God, or the destruction of the works of satan, demands total selflessness. And the greater the revelations of the Spirit, more humility is required. It is not known exactly what kind of thorn in the flesh Paul had. But surely, God allowed him to stay protected from pride.

Which is greater?

"Fools and blind! For which is greater, the gold or the temple that sanctifies the gold? [...] Fools and blind! For which is greater, the gift or the altar that sanctifies the gift?" Matthew 23.17-19

Tithes and offerings carry a revelation in itself: what is in the offering giver's heart.
Firstfruits show faithfulness and offerings reveal love.
While there was no sin in the world, tithes and offerings were not necessary, since the communion between the creature and the Creator was perfect. With sin came the moral and spiritual corruption. Therefore, God established the tithe and offerings to prove the heart of those who approached Him.

At the beginning of your suplications...

"At the beginning of your supplications the command went out, and I have come to tell you, for you are greatly beloved..." Daniel 9.23

Daniel made a purpose of fasting and prayer in search for a revelation and the Lord heard him. In the faith of Daniel, we will also seek, not a revelation, but the Spirit of the One who reveals. And those who engage in this faith will also be visited by the Baptizer, the Lord Jesus Christ.

BLESSED

"Then Jesus told him, 'Because you have seen me, you have believed; blessed are those who have not seen and yet have believed."             John 20.29

The certainty of God's existence is a revelation. Many haven't had the privilege of receiving this gift from God.   However, to those He has been revealed, this certainty goes far beyond any religiosity.
They possess a firm and unshakable conviction of receiving the reward for seeking Him.

FAMINE OF HEARING

"Behold, the days are coming," says the Lord God, "That I will send a famine on the land, not a famine of bread, nor a thirst for water, but of hearing the words of the Lord."Amos 8:11

Those who have been called, hunger for the Word of God. But, the chosen are the ones who put it into practice. To them, the arm of the Lord has been revealed.

Revelation

“ Let not the wise man glory in his wisdom, let not the mighty man glory in his might, nor let the rich man glory in his riches; But let him who glories glory in this, that he understands and knows Me, that I am the LORD, exercising lovingkindness, judgment, and righteousness in the earth. For in these I delight,” says the LORD."

Jeremiah 9.23

Nothing in this world can be bought through the glory of the practical knowledge of our Lord Jesus. It is a revelation from the Holy Spirit to those who are chosen.

Hear and keep

"Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near."

Revelation 1: 3

The prophetic words aren't just knowledge. They're to be put in practice, otherwise, there's no use in knowing them. In this case, reading, hearing, and keeping the prophecies from Revelations keeping vigilance of your soul's salvation, trusting that these promises will be fulfilled soon.
