What's so difficult?
God breathed life into us, but we had to choose Him (after He first chose us) to get abundant LIFE ! All men have breath, the 'breath of life,' but ONLY men (and women) who become His become NO LONGER LIVE BUT CHRIST LIVES IN THEM ! And, if that doesn't just coogle your coggle to know, then, you must be dead ! God is living in you, you in Him, ONCE you accept Him, and, who does Scripture say is in us, the HOly Spirit, right? So, IS God in us, or, is the HOly Spirit in us. BOTH ! BEcause they are BOTH God.
And, do I really need to explain Jesus to you? He is 'God in the flesh,' Scripture says that, not me. He is God with us, Emmanuel, right. And, Emmanuel refers to who? Jesus
One, two, three DIFFERENT manifestations of Himself, and, 'Himself' is God. Why can't God manifest Himself all over, why can't He, He is GOD ! LOL, Yeah, He can do it, NOTHING is impossible for God, with God, by God period And, the HOly Spirit helps (reveals) to us this truth, through Him who was God in the flesh, Jesus, on Earth, who shows us the way, the truth, and, the life.
Seems so simple, why complicate things
But, I know, the Lord works in His timing for us all and I just pray that through the revelation He gives you in Scripture, as you pray, you will see the truth of God being One, Not Two, and, certainly not, Three. One. He's a doppleganger, ahhhhh !! I'm being cute, but, also, that is the truth, God is the ONLY one who has the power of a doppleganger.
