THEN WHO OR WHAT HAS TAUGHT ME WHAT I KNOW ???????????

The answer is not a singular one, which it would appear you are expecting, eh? There are some/many things which the Spirit has brought to your knowledge and planted in your heart. But there are other things which are clearly NOT of God but of man..... and not necessarily men who are holding to the truth in one or more areas. It is also so important to realize that "knowledge" is not simply that which is embraced with the intellect. There is an "experimental knowledge", which is the resulting change in one's affections, desires and walk; aka, the "Fruit of the Spirit"; being conformed to the image of Christ, being made a partaker of the divine nature. There are several passages of Scripture which speak to this; a couple which come to mind most quickly are:

Colossians 1:9-10 (KJV) "For this cause we also, since the day we heard [it], do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding; That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God;"

2 Peter 1:4-8 (KJV) "Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust. And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge; And to knowledge temperance; and to temperance patience; and to patience godliness; And to godliness brotherly kindness; and to brotherly kindness charity. For if these things be in you, and abound, they make [you that ye shall] neither [be] barren nor unfruitful in the knowledge of our Lord Jesus Christ."
Perhaps you could devote some time to the truths contained in these two passages of Scripture and in self-examination.

In His Grace,
