51. Question: How does the glory of Christ, our Head, benefit us?
Answer: First, by His Holy Spirit He pours out heavenly gifts upon us, His members. Second, by His
power He defends and preserves us against all enemies.

52. Question: What comfort is it to you that Christ will come to judge the living and the dead?
Answer: In all my sorrow and persecution I lift up my head and eagerly await as judge from heaven the very same person who before has submitted Himself to the judgment of God for my sake, and has removed all the curse from me. He will cast all His and my enemies into everlasting condemnation, but He will take me and all His chosen ones to Himself into heavenly joy and glory.

33. Question: Why is He called God's only begotten Son, since we also are
children of God?
Answer: Because Christ alone is the eternal, natural Son of God. We, however, are children of God by adoption, through grace, for Christ's sake.
