A fourth practical implication of the ascension of Jesus for your life and mine is that we can reign with Christ now and extend his kingdom. Ephesians 2:6 says, "And God raised us up with Christ and seated us with him in the heavenly realms in Christ Jesus..." Because Jesus has ascended to heaven and is reigning there, we can reign with him spiritually.
How do we actualise our reign with Jesus? We do it by seeking to extend his kingdom through the power of the Spirit. Right before Jesus ascended to heaven he gave his first disciples a great promise. He said, "But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." (Acts 1:8)
I once had someone leave a church I was serving because, they said, "You focus too much on personal evangelism." If that was true, I praise God for it. As C. S. Lewis once said,
... the Church exists for nothing else but to draw men into Christ, to make them little Christs. If they are not doing that, all the cathedrals, clergy, missions, sermons, even the Bible itself, are simply a waste of time. God became Man for no other purpose. It is even doubtful, you know, whether the whole universe was created for any other purpose. (Mere Christianity)How do we contribute to that one goal of the Church? Certainly we do it through prayer. We also do it through speaking a word for Jesus here and there as the Spirit helps us. But mainly we do it by being, as Lewis also said, good advertisements for Christianity. The more we truly live out a relationship with Christ, the more that others will be drawn to the Jesus they see in us. As St. Francis is often quoted as having said, "Preach the Gospel at all times. If necessary, use words."
