Every key thing that John says in the clip lines up with scripture and true spiritual experience. By the Spirit, one readily agrees with what John says in the video clip.
Any one who truly understands and identifies with the Spirit knows that He can be very grieved when holiness is compromised. And that He can be sorely grieved when His name is blasphemed; He sends the Holy Ghost in His name. Many don't have a clue what the name of God encapsulates and means, let alone understand what Romans 1:18-23 means. To me, those verses of Scripture capture and summarize John's entire message.
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
19 Because that which may be known of God is manifest in them; for God hath shewed [it] unto them.
20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, [even] his eternal power and Godhead; so that they are without excuse:
21 Because that, when they knew God, they glorified [him] not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22 Professing themselves to be wise, they became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
John also confessed of his weakness when talking about how he was led to Romans 2:24 that declares: For the name of God is blasphemed among the Gentiles through you, as it is written.. That scripture was one of final straws to brake John and made him see his hopelessness given the culture of blasphemy in the community he was sent to. It is one thing to read scripture about that kind of grievous sin, it is another thing to believe it applies to you.
Job, at a point, felt like John before God gave him (Job) a deep and rude awakening to the knowledge of God that can indeed be experienced as a Father's loving chastisement. When God deals with you that way, you'd hate the very things you thought you were doing right and the doctrines you deeply believed as unshakable but were really of your carnal understanding. His righteousness is faultless and excellently credible.
I haven't heard a teaching (for the discerning) in a very long time like I heard from John in that video clip. John's teaching does impart a weighty measure the grace of God to those who believe and can see to receive.
Let those who have an ear listen to what the Spirit is saying to the saints.
