But he that is joined unto the Lord is one spirit. (1 Corinthians 6:17)
“The phrase, ‘in Christ’ is never translated to mean anything else except, ‘in union with Christ.'” – Mark Hankins
Important prepositions normally go unnoticed in Paul’s Epistles. The words for, with, in, by, and through help us understand our identification with Christ. They are the connecting words that show the relationship of the subjects mentioned, in this case, the believer’s identification with Christ.
The preposition for shows substitution. Christ died “for” us or in our behalf. The preposition with shows identification. The preposition in shows union with Christ. The preposition through shows application. For example: “I can do all things through Christ which strengtheneth me.”(Philippians 4:13)
When you were born again, your spirit was joined to the Master, or joined to Christ. Like a bay of water is one with the ocean, your spirit is one with Christ. When the water rises in the ocean, it rises in the bay. The same stuff that is in Christ right now is in you — the same life, the same victory, the same joy, and the same power!
Confession: I am born again. My spirit is joined to Christ. The same life, victory, joy, and power that is in Christ Jesus is in me now!
