When you were dead ... he made you alive

Paul speaks of unresponsiveness to God as if it were death, while he also speaks of coming into new spiritual life as if it were coming back to life physically. Alternate translation: "When you Colossian believers were unable to respond to God"

dead in your trespasses and in the uncircumcision of your flesh

You were dead on two accounts: 1) you were spiritually dead, living a life of sin against Christ and 2) you were not circumcised according to the law of Moses.

forgave us all of our trespasses

"he forgave us, both us Jews and you Gentiles, of all our trespasses"
