In this verse, the angel Gabriel is announcing to Mary the future greatness of her son, Jesus. The promise that Jesus will reign over Jacob's descendants forever signifies the fulfillment of God's covenant with Israel. Jacob, also known as Israel, represents the chosen people of God, and Jesus' reign over them symbolizes His role as the Messiah, the anointed one sent to bring salvation.
The phrase 'his kingdom will never end' is a powerful declaration of the eternal nature of Jesus' reign. Unlike earthly kingdoms that rise and fall, the kingdom of Christ is everlasting. This provides a profound sense of hope and assurance to believers, as it underscores the unchanging and eternal nature of God's promises. Jesus' kingdom is not limited by time or geography, and it transcends all earthly powers.
For Christians, this verse is a reminder of the enduring presence and authority of Christ in their lives. It calls them to live in the light of His eternal kingdom, trusting in His guidance and sovereignty. The verse also encourages believers to look beyond the temporary struggles of this world and focus on the eternal hope found in Jesus.
