What motivates people to get involved in world missions?

Obviously, the Holy Spirit is the one that puts callings on our lives, but he can do that through a lot of different methods and delivery systems. I've discovered three ways (and I'd love to hear any others that you come up with) to get people excited about praying, giving, and going. Which of the following stirs you the most to get involved in missions and makes you want to pray, give, and go to the unreached?

1) The Isaiah pathway - This is basically getting so caught up in God that you can't help but have a heart for the unreached. As we hang out with God, we become more like Him and we know that one of His characteristics is that he wants all to be saved. It was while Isaiah was in the presence of God with angels worshiping that he got to the point of saying "Here I am, send me". Louie Giglio always says that "as you get lost in wonder, you can't help but wander about the lost." His team has a huge heart for the nations and do large Passion Conferences to get people excited about God which in turn should lead to more people serving in missions.

2) The "open your eyes" pathway - This is basically making people aware of the needs around the world to spur people to involvement in missions. Jesus told the disciples to open their eyes and look at the harvest field and reminded them how few laborers are going. He told them to pray to the Lord of the harvest for more laborers and in the very next breath said "go". Hearing statistics about how many unreached people groups are left, how many missionaries are serving in those areas, and how much of our church money is sent to the unreached is a big motivator for many. Organizations like Joshua Project might be considered strong in this pathway.

3) The "the harvest is ripe" pathway - This is a little bit of a tweak on the second pathway in that this is focusing more on the positive things that are going on in the world rather than the remaining need. Don't you get excited when you hear about a supernatural healing overseas? Don't you love to hear stories about how many people are coming to know Christ in Africa each day? Hearing that God is moving in a certain area spurs many people into action. Joel News is a good example of a newsletter that tells about some of the exciting things that are going on in the missions world.

How about you? What have you found to be some of the most motivating things to make you want to go and make the name of Christ great among the nations?
