What does the title 'Son of God' signify in relation to Christ's authority?

The title 'Son of God' is crucial in understanding the person and work of Jesus Christ. It denotes not just His divine nature but also His authority as the appointed Savior and ruler over all creation. John 10:30 states, 'I and the Father are one,' emphasizing the unity of purpose and essence between the Father and the Son. This relationship grants Christ His authority, given to Him for the specific purpose of salvation, as articulated in John 17:2, where He indicates that He has the power to grant eternal life to those given to Him by the Father.

Furthermore, this title implicates His role as the one who fulfills the covenant promises made throughout the Old Testament. It is through His unique sonship that believers are able to call God 'Father' as well, thereby establishing a relationship founded on grace. Understanding Jesus as the Son of God brings clarity to His authority in the tasks of judgment and salvation, highlighting His role in the overarching narrative of God's plan for redemption.
