That the world don't acknowledge God in their welfare don't mean as a child of God you should tow the same line. When we don't acknowledge God as the Source of what we have, serving His cause with what we have will become a great challenge. Selfishness has never served the purpose of God. No one became anything all by himself. Such thinking breeds selfishness in every way. No one is self-made. God has put in man ability to do things. If the world don't acknowledge it you mustn't tow that line too.
