The Hope of Righteousness Galatians 5:5

Why does the Bible teach the "hope of righteousness" if the concept of reighteousness was fulfilled on the day of Pentecost? Did not Daniel speak about the coming of "everlasting righteousness" at the completion of the 70 weeks prophecy, Dan. 9:24? Were the 70 weeks fulfilled on Pentecost? Did not Peter also say he looked for a new heavens and a new earth wherein righteousness dwells? How do we reconciled these passages. The answers are found in this study.
