And He died for all, so that they who live might no longer live for themselves, but for Him who died and rose again on their behalf. 2Cor. 5:15
Your working field
Imagine to trod jungle paths to reach people, to go to city slums to seek the destitute, stand alongside farmers to plant rice, dig water wells, lay bricks or invest time and energy in child care etc. etc. Think of a job or task, think of working with your hands or head, and there is a vacancy in mission.
God wants to use YOU
Would there be anything more fulfilling in your life but when God will use you to show His love and care for people? He can use you to help and solve physical needs, but He can also ask you to bring people to Himself, to the Source of Life. Would you like that?
Your motives
Be honest to yourself! What are the real motives when you think of a job or task in mission? Is it first of all to bring people closer to Gods warm heart? Or are there other motives playing a role also, such as:

My first reason to go into mission is to spread the Gospel of Jesus Christ

I chose to let God determine my life

I have my "quiet time" with God on a regular basis and mission is in my prayers

I can make and keep friendships

And when you are married: my family supports my desire to go into mission

we have a stable relation in our marriage

My home church backs me up when I would decide for mission.
