Who is included in the 'us' mentioned by Jesus?

The 'us' that Jesus refers to is inclusive of all who are united to Him by faith. In John 17:9-20, Jesus specifies that He prays not for the world, but for those whom the Father has given Him—this includes all believers throughout time. The notion of 'us' signifies God’s chosen people who have been selected for salvation. This corporate identity is crucial for understanding how believers partake in Christ's achievements, specifically in fulfilling all righteousness. Therefore, any person who believes in Christ and accepts Him as their righteousness is included in this 'us'.
