A mobilizer is one who uses his/her influence to help others become World Christians (Christians with a passion to reach the unreached with the Gospel.)
Being a mobilizer will naturally happen as you grow in your passion and commitment to fulfilling the Great Commission. As you learn, pray, go, send and welcome, bring others along in your journey.
Make disciples. As you make disciples, complete the discipleship process by equipping them to be World Christians who learn, pray, go, send, welcome and mobilize themselves. Guide them through this process, and you will be richly rewarded as you see them bear fruit as World Christian disciple-makers.
So pray to the Lord who is in charge of the harvest; ask him to send more workers into his fields. -Jesus (Matthew 9:38)
