Firstly, what is meant to be holy? The apex Question here right?
To be Holy means not connected or attached to something that is not GODLY or to be devoted to God faithful and righteous ways. While mystery means something that is hidden and intended to be kept ‘’except for those that search for it’’ and who are they? They are those that are HOLY.
Holiness is not something that Christians should take with levity hands because you must be holy if you want to commune with GOD, for our God is a spirit and holy to the extent that you can’t go to him [worship or pray] with mere flesh. When you are holy, you have a divine life in you i.e the Holy Spirit. Being the third personality of the trinity [The Father, The Son and The Holy Spirit] he will helps you to make it easy to know and communicate with God.
For one to be rapturable, one has to be baptized in the Holy Ghost because flesh is not allowed in the kingdom.
There are so many benefits attached to being holy, you too will enjoy your life because it will be control by the divine being [Holy Spirit].
Mary was holy; she gave birth to our savior [Jesus Christ].
Esther didn’t defile herself, she was made the queen.
Elijah walked with the Lord and was carried away with chariot of fire.
Holiness gives rise to the revelation of mystery, when you walk with God perfectly he will show you hidden things because deep calleth unto deep and the secret of God is with those that feareth Him. If you fear God automatically you will be holy and righteous because you won’t want to do what God hates most which is SIN.
Who shall go up into the mountain of the Lord? Or who shall stand in His Holy place? He who has clean hands and a pure heart, who has not lifted himself up to falsehood or to what is false nor sworn deceitfully.
We can see now that we have to be holy before we can go into His presence because He is Holy and you cannot see HIM with your physical, mere or sinful eyes. He is too holy, righteous and powerful that the face of a sinner cannot behold His glory. The grace of God can only be with all the saints, that’s God holy people [those set apart for God]. Except you are holy you cannot be allowed to enter the city of holiness which is heaven because no blemish or dirt can be allow to enters there, it is full of purity.
In conclusion
Revelation is different from Revelation, God shows deep hidden things to only those that are closer to Him and that kind of revelation is called DIVINE REVELATION but to be count worthy of such revelation one have to understand the mystery of being Holy and the ways of the Holy minds [i.e Co-heirs/Royal priesthoods].
“Blessed are the pure in heart for they shall see God”
Lastly, be holy and let your life be a picture of him, let your life be a letter written by his hand in his own divine handwritten because a Holy life is a fulfill life right on earth and also a life that will be welcome with joyful and tremendous noises at the very end. Will yours be inclusive too? The only way you can be inclusive is to strive for the whole of your living to be Holy and righteous in his presence and then HE will show you the mystery of being Holy.
