Our Ministry
ISA is designed to help those who have been called to live on the foreign missions field, fulfilling Jesus' commission to the disciples, "Go unto all the world and preach the gospel to all creation." (Mark 16:15)
Our goal is to work alongside of missionaries on the field, making it possible for them to be able to concentrate on the work at hand and not on the work at "home".
ISA is recognized as a 501(C)3 nonprofit corporation in the USA, for the purpose of servicing and assisting the work of missionaries in the field through various services.
Contributions to associate missionaries are tax deductible and receipted yearly.
