1 Corinthians 1:6-8

In this way our testimony about Christ was confirmed and established in you, so that you are not lacking in any spiritual gift [which comes from the Holy Spirit], as you eagerly wait [with confident trust] for the revelation of our Lord Jesus Christ [when He returns]. And He will also confirm you to the end [keeping you strong and free of any accusation, so that you will be] blameless and beyond reproach in the day [of the return] of our Lord Jesus Christ.
