When it comes to evangelism and missions, Jesus wants us to show the world what a citizen of the kingdom looks like. Immediately after the beatitudes in Matthew 5 we hear Jesus saying “You are the salt of the earth” and “You are the light of the world” (Matt. 5:13, 14, NIV). (Paul says something similar in Philippians 2:14-16.) Then he gives the command “Let your light shine before others, that they may see your good deeds and glorify your Father in heaven” (Matt. 5:16, NIV).
Thus, after explaining what kind of people his disciples should be, he directs them to go out and display the kingdom of God in their lives. His point is that when others see what the kingdom looks like in us, then some of them will also become people who glorify – display – God and his kingdom. God is looking for seekers who will desire good over bad, the constructive over the destructive, purity over corruption (see Acts 10:35). He wants to use us to draw those people to him.
This brings up a very important point on the issue of missions and evangelism. What is the most important evidence for Christianity that we can present to the lost? What is most persuasive? Isn’t it the fruits of the Spirit of Christ shining through us? Isn’t it the experience of seeing reflections of Jesus in us that will draw God’s chosen ones to him? I believe it is important to bring the supernatural power of God for physical healing when we do missions (even next door) as well as other manifestations of kingdom power. It is also important to provide physical help, such as food, clothing, water, housing, and finances. But the most persuasive evidence of Jesus is Jesus in us. Shouldn’t our missions strategies make this their highest priority for reaching the lost?
