The mission of God is attractional and incarnational.
I don’t know why, but I have a fascination with yo-yos. Now, I can’t yo-yo. Nevertheless, I find it amusing and entertaining as a skilled yo-yoer (if I can use that term) cast the yo-yo out with great rhythmic force only to have it return with an energetic bounce to be cast back out and to come back to its starting place.
I often use the yo-yo and it’s movement as a way to describe God’s mission. Just as a yo-yo, when properly used, has a 'going out' and 'coming in' function, so too does God’s mission. Missiologists sometimes refer to this going out and coming in as the centripetal and centrifugal forces (movements) of God’s mission.

As Israel embodied and enacted the life of God (i.e., the Kingdom of God), they were to be an 'attractive sign' to a watching world.
The centripetal movement of God’s mission remains as part of God’s missional call for the New Testament people of God. In the Sermon on the Mount, Jesus taught His followers, “You are the salt of the earth. . . . You are the light of the world. . . .[L]et you light shine before men, so that they may see your good works and give glory to your Father in heaven” (Matt. 5:13, 14, 16). Peter uses similar language found in his epistle (1 Pet. 2:9–12).
