No it is not.Duh
Scripture is the revelation of the Spirit
The Spirit reveals the truth in scripture. Have you not read that the letter kills but that the Spirit gives life.
The Spirit of God gives revelation. You and others devoid of the Spirit can read scripture as much as you want and then post a wall of scripture you think supports your heresy. That is a tactic used by all false teachers who want to change the meaning of scripture like 2 Cor 2.
Scripture contains the required information for the Spirit of God to give revelation. That is what your cut and paste scriptures teach us.
As a false teacher you have to insist that you do not NEED God to give you revelation, you are capable of understanding it all devoid of the Spirit of God.
BTW, the gospel is the POWER of God unto salvation. People hear the gospel preached without reading the scripture (Read Acts 2) and they are convicted by God. Scripture is not the power of God unto salvation, otherwise everyone who ever read the Bible would be saved.
As it stands, you and atheists are in the same boat, both parties lean on their own understanding and miss the Spiritual completely, leaving you as corrupt as you were yesterday, and the day before.
So Duh, you can tell people to lean on their own understanding which you pretend to be revelation all you want. It does not make you any less of a false teacher.
