God is Christ and Christ is God, and God did die on the cross.
God wasn’t in Christ. God is Christ!
You are right that God, the Holy Spirit was in Christ, but Christ is God, and the Holy Spirit is God. So God is Christ and God is in Christ, and God rules over Christ. All at the same time.
**God did die on the cross.**
FRiend, you’re stuck in man-made, ‘mother of God’, theology.
God is a Spirit. All the nukes in the world cannot kill even a portion of his Spirit. It’s a domain we can hardly comprehend. But the flesh of Christ was made, which marks a beginning. God is from everlasting to everlasting. No beginning, no ending. No weakening......ever, let alone dying for even a second.
**God wasn’t in Christ. God is Christ!**
God is Christ, only if you’re referring to the Father dwelling in him. Most notably in John chapters 5, 8, 10, 14, 15, and 16, Jesus Christ spoke a great deal about ‘the Father’ in him, teaching him all things, telling what to say, doing the ‘works’, etc. When speaking of God dwelling in himself, the Christ calls him the Father, not the Holy Ghost. Why? Read on.
That’s because it pleased the Father that IN him (Christ) should ALL fulness dwell (Col. 1:19). Not just a portion of the Spirit of God dwells in him, but the fulness of God the Father. That’s how the Christ has all power.
The tabernacle of flesh, in which God appeared to man, could not survive the crucifiction, but God raised him up (Acts 2:32; 10:40; 13:37; 17:31, all point this out without mentioning any ‘separate and distinct persons of God’ performing this miracle).
God almighty is one, yet cannot be measured. That’s the great mystery that man can’t grasp.
Here’s a riddle for you: Why is the term ‘God the Father’ found in scripture, but the term ‘God the Holy Ghost’(Spirit) not; and why is Jesus Christ never referred to as ‘God the Son’, but ‘the Son of God’?
It is SO simple. God the Father, the only God there is, gives of his Spirit (Luke 11:13; Acts 5:30-32), and the same Father dwells in his Son and his Son in him.
