"Both righteous and sinful"

"Ligoner National Conference - John MacArthur - We Have Been Raised But We Stink"

In the last part of Challies' synthesis of MacArthur's sermon, which includes discussion of justification and sanctification, he writes:

Putting sin to death is a lifelong process and one that will be perfected only in the day of Jesus Christ. Until then we are and shall remain both righteous and sinful.
