Helpful words for the missionary or missions team member

We have been asked and have ourselves asked, how can we help the people here when the need is so great and our resources are very limited. It's the question that has reoccurred daily since being here.
A mission team is coming down in March from our home church, Sarasota Alliance Church, so we've been trying to put together some helpful documents to prepare them for facing what they will experience in Haiti.
One of things done for teams is the field training guide, it's a twelve unit study for preparing to go on a missions trip. Jennifer asked me to read it over before sending it to the team leader from our church.
This is written on the fourth page,
What is a missionary? "Jesus said to them again, As the Father has sent Me, I also send you"(John 20:21). A missionary is someone sent by Jesus Christ just as He was sent by God. The great controlling factor is NOT the needs of people, but the command of Jesus. The source of our inspiration in our service for God is behind us, not ahead of us. The tendency today is to put the inspiration out in front to sweep everything together in front of us and make it conform to our definition of success. But in the New Testament the inspiration is put behind us, and is the Lord Jesus Himself. The goal is to be true to Him, to carry out His plans.
Personal attachment to the Lord Jesus and to His perspective is the one thing that must not be overlooked. In missionary work the great danger is that God's call will be replaced by the needs of the people, to the point that human sympathy for those needs will absolutely overwhelm the meaning of being sent by Jesus. The needs are so enormous, and the conditions so difficult, that every power of the mind falters and fails. We tend to forget that the one great reason underneath all missionary work is not primarily the elevation of the people, their education, nor their needs, But is first and foremost the command of Jesus Christ, " Go therefore and make disciples of all the nations..."(Matthew 28:19). From My utmost for His Highest, 1963, Oswald Chambers.
These words just echoed my my head, over and over. Question answered, disciples first, needs etc. as God provides.
Wish I would have read these words along time ago, so I'm sharing it with you, hopefully, before you go out on the mission field.
