Paul talks about the ways in which Christ is excellent.
“God the Father has rescued”
“Darkness” here is a metonym for evil. AT: “the area controlled by evil forces” (See: rc://en/ta/man/translate/figs-metaphor)
“God the Father’s beloved Son, Jesus Christ”
Paul often speaks as if the believers were “in” Jesus Christ or “in” God. AT: “By means of his Son we have redemption” (See: rc://en/ta/man/translate/figs-metaphor)
“redemption; his Son forgives our sins” or “redemption; the Father forgives us through his Son”
