You know that that is an excellent place to start. I am with this article in so many ways. When God opens up His Word to speak to your heart. The Words lift off the page and enter into your heart in a personal way that is not the course of the written. It transcends the historical or prophetic position and gets real in your own life and world around you. But there is more to this.
Rev 3:20 is a promise of a one on one "face to face" conversation. The thing with this is that you have to repent of all your sins, and ask God to reveal even more. The secret sins, the sins long forgotten, the little sins, the favorite sins, are all brought forward. Even sins you didn't know were sins. God will reveal to you the sins that keep you from His Presence. If you keep accepting the depth of sins you need to repent of, the breath of sins and how the roots and branches have affected not only you, your family, and friends but untold multitude, then you really begin to realize the size of the schism between you and God. You also begin to realize how sin is seen in His Presence. He can not come to visit with you because you could not live in His Presence in your current state. Solution... Once God has revealed to you just how unworthy you are, and how much you need to repent of just to visit with Him, He will forgive you through the blood of Yeshua. He will lay upon your shoulders His robe of righteousness so that you may stand before Him. He will then clock Himself in His clearness. But even with all that, You will be overwhelmed with His Holy Presence.
You will be like Isaiah crying out "woe is me". You will be blown away in spirit and trembling in awe. He will lay His hand upon you, and you will be washed and made clean. You can then talk with Him. One of the most fascinating things is that everything He says is back up by scripture. Scripture comes alive and the Words of God are flowing like many waters of truth and grace. At this time, you can ask all the questions your heart desire to know, and He will answer even if it is a yea or nah, even if He has to take you in vision so that you can see it. Time will have no relevance when in His Presence.
God is real, get real with God. I spent over six months with no other thought on my mind but finding out what it takes to be in His Presence, what it is like, and what can I expect. This bible study on this subject was bathed in prayers for His guidance and leading. I wanted Him. I wasn't interested in doctrines, theology, or someone's opinion. I wanted to "know" Him just like the people in the bible got to know Him. Every person in the Bible that met with Him, I looked for what they saw, they experienced, they felt, and what they heard. I wanted to "know" this God of the Bible so that I knew it was Him.
One of the most powerful things is His "Holy" Presence. There is non "Holy" in the real sense of the word. People may put it on doors, bibles, altars, etc... but that doesn't make it truly "Holy". "Holy" is the very essence of Him. It emanates from Him. You can only come so close but no closer.
Even in Heaven, there is only one who is able to come into His Holy Presence and see Him face to face. That is Yeshua. He is the flesh of God. Have you ever wondered why many will be crying out to the rock, fall on us, hid us from His Presence. It is because of His "Holy" Presence.
There is nothing on earth that can truly do it justice in trying to describe "Holy". You have to experience it in order to even begin to truly understand. If we do not choose to come to Him now, there is no way we will be able to face Him when He comes in all His glory. Those who have the foretaste know what to prepare for. The rest will be overwhelmed.
Sin hangs off you like snot in His Presence. It melts and if He comes in all His glory it will consume you. Not because He wanted that to happen, but because that is what happens to sin and sinner in His glorious full blast, "Holy" Presence at the second coming.
