Note that the place where believers exist is InChrist Jesus. Since Jesus is a physical being the only way we can be In Christ is when we are in His HolySpirit and His HolySpirit is in us.
It was His love that led the HolySpirit to make Himself a body to be the sacrifice for our sins so that we can be in intimate personal relationship with Him.
In coming into us and us into Him we have His righteousness and His life. It is all a free gift that we receive by faith in the Gospel of Jesus Christ.
The FaithOfChrist is our anchor. We trust in Him -> who He is -> what He said -> what He did
and thereby we are found in Him.
