I believe the central goal of missionary work is the planting of local churches. There is no other substitute for this.
Whatever the missionary does, it should be with the aim of starting a new church or nurturing one that is already in existence.
Church planting is not easy.
The missionary labors in an alien culture controlled by Satan, whose government and citizens often are not friendly to the Gospel.
The missionary is tempted to become sidetracked and substitute other activities in the place of church planting.
Some want to specialize in some particular effort, which they enjoy but do not have any direct connection with the task of church planting.
Such temptations should be resisted.
Our goal is to produce self-sustaining and self-propagating churches. In other words, churches that will stand on their own without being propped up by missionary dollars or led by missionary pastors.
We desire churches that will be pastored by national believers who are well trained in the Scriptures. Their own members should financially support these churches.
In some cultures this is a challenging and difficult task, but it is, nevertheless, a goal, which is mandated in Scripture.
To produce church leaders indigenous to the country requires diligent training in programs established for that purpose.
One of the missionary’s chief concerns should be the development of godly and competent leadership.
