As I have pondered over the age range in this conference with a huge group of younger people

and a modest group in the middle and a few people like me at the

upper end. What has come to the front of my mind is that there are peculiar obstacles for each of those

groups to global missions, obstacles to full, red-blooded,

unintiminated, uncompromising engagement in world evangelization.

This is a conference about missions and for me that means you being mobilized either

senders or goers to reach the least reach peoples in the world.

These obstacles that I have in mind, three of them,

may not be the biggest ones for you or in your generation, but they're the ones that I feel burdened

to address in which I believe God has given me a word for.

So I want to begin by naming the obstacles

for each of those generations, the younger, the middle and the older, and then

direct your attention to a passage in Philippians where God will address those obstacles and he will show

that the invincible power of joy is the means of overcoming those three obstacles.

Number one, I'm thinking here of the youngest of the youngest.

In other words, the 18 to 40 group,

I'm thinking toward the front end,

It takes the form of opposing those whose message you don't like by claiming

that you don't feel safe when they talk.

In other words, you protect yourself
