How do we know Jesus Christ is going to be the judge?

John 5:22-23 emphasizes that the Father has entrusted all judgment to the Son, demonstrating the authority given to Jesus as the appointed judge. The resurrection of Christ from the dead serves as the definitive evidence of His power and authority to execute judgment. This authority confirms that Christ will judge righteously and justly, based on His perfection and holiness, and not by any standard other than His own righteousness. Acts 17:31 also supports this, stating that He will judge the world in righteousness, underscoring the certainty and seriousness of this future reality.
