The penalty of sin is death. Death is a state of existence involving separation. The testimony of Christ Jesus on the Cross manifests that separation.
The resurrection manifests God the Father returned the human spirit to the body of Jesus Christ in the new body, the first fruits.
G-d never took on human form. It is heresy.
He made it very clear that He is not a mortal,that He can’t be seen and that He has no human features.
So,G-d separated Himself from j-sus when j-sus died on the cross and then proceeded to reunite with j-sus after the resurrection?
Makes perfect sense....
