But previously, you said:
And even if God didn't call him for this people, no where in the Bible will you find man needing to ask for permission to reach a people for Christ. He was obeying the very first commandment to Adam that never changed: subdue the earth.
So why arent you subduing these islanders? You dont need Gods direction in these matters, you have standing orders.
How God calls is not the issue here. Jesus Christ and His gospel is your problem. You are at decision time. God used a servant of his to present you (and billions of others) a gracious opportunity to understand the good news of Christ because He loves you.
