"quickened-together-with" Christ, [is a word that] does not somehow mean that Christ Himself had not the Spirit one day, and the next He did... or anything like that. [see verses 3-6, along with the broader context, esp the "us" and then the "you also" of 1:13]
This word is used also in Colossians 2:12-13 ([where also is said, "buried with Him in the baptism"] and to be viewed in the wider context of Colossians 2:6,9,10-17, where v.13 states, "being dead in your sins and the uncircumcision of your flesh..."; and where verse 17 says of "the list of things," "Which are a shadow of the things coming [i.e. the future things, not in "this present age"]; but the body is of Christ").
