Romans 6:21-22

²¹ What fruit did you have then in the things of which you are now ashamed? For the end of those things is death.

²² But now having been set free from sin, and having become slaves of God, you have your fruit to holiness, and the end, everlasting life.

end (in both verses) = limit, final result of a process

death (v.21) = not merely physical but in its most comprehensive state

become slaves (v.22) — as in verse 18, not the act of the individual, but by God’s power consequent on the individual’s faith

holiness = sanctification as in verse 19
