The Ascension of Jesus is not merely a historical event but a profound declaration of His lordship over all creation, as affirmed through Scripture in Daniel, Ephesians, and Acts. Jesus is exalted as Lord—above every authority, power, and name—because He has risen from the dead, is immortal, and now reigns at the right hand of God, exercising ultimate dominion over heaven and earth. His lordship is not only political and cosmic but also spiritual, as He is the head of the church, the only mediator through whom true worship and access to God are possible. This truth demands total submission from believers, who are called to live in obedience to Jesus in every area of life, especially in fulfilling the Great Commission, which must be the church's central mission. The sermon challenges Christians to examine whether their lives reflect a genuine allegiance to Jesus as Lord, urging repentance from hypocrisy and a renewed commitment to evangelism, prayer, and surrender, knowing that every person will one day stand before Him in judgment.
