God is Triune. He has been from Eternity. IS (as we mere mortals “see” time).
He will be for Eternity. His Triuness includes the concept of Father, the concept
of Son, and the concept of Holy Spirit. All are equally eternal.
Is this a Biblical teaching? Remove all doubt. Take the time to look up (this
afternoon or at your earliest convenience) the following references:
Joh 1.33
Act 10.38
Act 20.28
Rom 8.27
Rom 15.16
1Co 6.11
2Co 13.14
Gal 4.6
Eph 2.18
Heb 9.14
Heb 10.29
1Pe 1.2
1Pe 3.18
1Jo 4.2
1Jo 5.7.
These do not include the few times the Entire Trinity is shown but is spread across two or more near verses.
The Bible is under attack. Concepts, basic teachings, doctrines about God and His Book are under attack. One thing is the Divine Trinity.
One reason some reject the Trinity is they cannot understand It. “Welcome to the club” – no human understands the Trinity. (We will perhaps understand the concept of the Trinity better as we progress through Eternity but don’t be surprised if we never fully grasp this Lofty, Holy arrangement.
But then, would God be God if we understood Him? We are mere creators (He is the One and Only Creator) and we do not understand ourselves – it should come as no surprise that we do not grasp the Greatness of our God.
Those who knowingly deny the Trinity are to be pitied and prayed for.
