How do we know that Jesus is King in the kingdom of heaven?

The affirmation of Jesus as King in the kingdom of heaven is poignantly illustrated through His resurrection, which serves as a divine endorsement of His authority. In Psalm 2, God declares, 'Thou art my Son; this day have I begotten thee,' indicating that Jesus' resurrection marks the fulfillment of prophetic scripture and God's decree to place Him on His holy throne. Acts 13 highlights this truth as Paul refers to Jesus being raised up by God, applying the declaration of Psalm 2 to affirm Jesus' position.

Furthermore, Hebrews 1:3 states that Jesus, having purified our sins, sat down at the right hand of God, establishing His reign over all creation. His exaltation is an essential aspect of His kingship, signifying the start of His governance and the unfolding of the kingdom of heaven among His people. Therefore, the resurrection not only confirms Jesus as King but also initiates the age of His kingdom, empowering His followers with the gospel for transformation and salvation.
