For through Him we both have our access in one Spirit to the Father. Ephesians 2:18
Who can understand The Trinity? A mystery that many theologians try to explain, some who can’t explain The Trinity just end up denying it. The problem with going down this road is you are denying the Deity of Christ. They then need to explain how Jesus forgave sin, raised the dead, and allowed many to worship him.
Paul here reveals about the Trinity
“For through “Jesus” we both have our access in one “Holy Spirit” to the “Father God” (Ephesians 2:18)
We remember that Jesus said he is the only way to God The Father (John 14:6) So those who are trying to cut out “The Son” as part of the Trinity and go directly to The Father will fail. We are not worthy or able to stand before God alone, we need the ransom blood of Jesus Christ to make us worthy.
So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, Ephesians 2:19
Paul explains this, without Jesus Christ we are strangers and aliens to God. Only by the blood of Jesus Christ and the baptizing of The Holy Spirit can we then become Children of God
having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, Ephesians 2:20
Jesus is the chief cornerstone , to reject the Trinity is to reject Jesus Christ. And when you reject the cornerstone of our faith, your religion crumbles.
in whom the whole building, being fitted together, is growing into a holy temple in the Lord, Ephesians 2:21
Now we see where the Holy Spirit comes in, we being resurrected with Christ, made a new person are the Temple of God (1 Corinthians 3:16) And when you receive Christ , the Holy Spirit will dwell in you
in whom you also are being built together into a dwelling of God in the Spirit Ephesians 2:22
Through the Holy Spirit we are connected to God The Father. As Jesus taught us in John 14, he sent The Holy Spirit to live with us forever to comfort, advocate, and guide us in Jesus Name Amen!
