We are not given a choice. The scriptures tells us plainly we are to go into all the world.. It is called the Great Commission. You cannot get around that in any manner that you might try.
Second: we have been told in scriptures that to whom much has been given , much is also required.
Thirdly: it is not about us and them it is about WE. you cannot seperate the body of Christ in groups of those outside the US and those inside the US. That is in no way scriptural and is contrary to the word, and the understanding of one body.
As I have mentioned before the problem is that to many view missions as a burden and not an opportunity. That is the fault of the leadership at your IO.
Fourthly: If it is not based on meaningful relationship between the pastor and the missionary, escecially if that missionary is a notional, it will not be effective no matter how much money you send. Without relationship they will smile at yuou while taking your money and when you leave they will do what they think necessary.
Fifth: their is a vast misunderstanding of what support really means. We think of support as dollars leaving our pocket and going into the pocket of another. We do not view it as building God's kingdom. We fail to realize that if we build His kingdom Christ made us a promise that He would build the church.
So where is the problem. Not in giving to missions, but in a complete lack of understanding about how funds are distributed, and how they are used to provide the proper tools that others, they themself can build the kingdom and reach their nation for Christ.
Having pastored here in the states many many years and planting churches from scratch..I am more than aware of finances...I paid the church payment, I bought the toliet paper and light bulbs. If I hadn't paid tithes off my secular job there would not have been any tithes.
Now I am faced with raising hundred's of thousands of dollars yearly to build God's kingdom around the world. so I have a better picture than many. I have no denomination supporting me. We starteed from scratch 12 years ago.
The sooner we understand about placing tools in the hands of other we can and will see much more accomplished and others becoming self sufficient enough to carry their own weight.
I know there is much resistance to this... I personally have offered real tangible tools to help build buildings and train leaders to other organization including cogop. never to hear from them.. Why? I quess they all know better approaches and after all I am just an outsider.

You cannot effectively love and minister to others when you are obsessed with protecting
and preserving yourself.
