If there was one reason why God sent me to live and work in a foreign land, less prosperous than the one I came from, then this verse says is beautifully: Philippians 4 verse 10-13
Thanks for Their Gifts
10 I rejoiced greatly in the Lord that at last you renewed your concern for me. Indeed, you were concerned, but you had no opportunity to show it. 11 I am not saying this because I am in need, for I have learned to be content whatever the circumstances. 12 I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. 13 I can do all this through him who gives me strength.
