Okaaayy....this is getting a little disturbing, brother.
If you can find scriptural support for those lesser truths you've pointed out, well and good. But if you can't...please, for your sake and those to whom you share these insights, abandon such beliefs!
I'm no theologian, but i'm sure those lesser truths are completely unbiblical. They rely so much on man's vain attempts to understand the mysteries of GOD's being and HIS creation. GOD is Spirit, not mere energy! And as much as we would like to think so, we cannot see GOD in near death experiences. If that were the case, HE'd state it in HIS Word that HE'll speak to us through such circumstances. The Bible is written, so that all GOD's truths that we need concerning knowing HIM, HIS love and HIS will for our lives and for the Church are there. No more and no less. Take it or leave it. If you truly want to seek GOD and understand HIM, please do so by prayer and in studying HIS Word, asking for HIS wisdom and discernment. If you long to understand the wonders that only GOD can reveal to you through HIS Word, ask for the gift of Prophecy, then. There is no gift of Mysticism in the Bible, brother. As eager as you are to discover GOD in all HIS wonder and glory, trying different schools of thought towards increased awareness and higher knowledge of the divine, you are now skating over thin ice, under which is a straight downward plummet into the enemy's oblivion...
Romans 11:33-36
King James Version (KJV)
33 O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out!
34 For who hath known the mind of the Lord? or who hath been his counsellor?
35 Or who hath first given to him, and it shall be recompensed unto him again?
36 For of him, and through him, and to him, are all things: to whom be glory for ever. Amen.
1 Corinthians 1:25
King James Version (KJV)
25 Because the foolishness of God is wiser than men; and the weakness of God is stronger than men
I will pray for you, brother. Please do not take offense, but instead, examine your heart and mind if it is in the right place. What would you have to lose by doing so? For we are all learning and growing deeper in the knowledge and the love of our LORD. We need HIS guidance in our lives continually, everyday. So please do not ignore this reproof done with much love from our GOD through the brethren.
GOD bless you, transform and renew your mind, as you submit your all, heart, body, mind and soul to HIM.
2 Corinthians 10:5
King James Version (KJV)
5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
Psalm 139:23-24
King James Version (KJV)
23 Search me, O God, and know my heart: try me, and know my thoughts:
24 And see if there be any wicked way in me, and lead me in the way everlasting.
