All that says is to seek a being called god. It sounds like if I seek him then I will never want for anything. So there are no poor Christians?
It isn't what it is saying, the person here speaking is Jesus Of Nazareth His Pre-Eminence who is the GOD HIMSELF. And HE is revealing that if they seek the kingdom of GOD and HIS rightousness, they will discover how to be born again so they cannot die anymore. And a person that cannot die, has no need for food, or drink, or clothing, because that kind of body has not the need for them.
Seeking the GOD is not something anyone can force you to do, its something that you choose to do because of your innate desire to know HIM. And the seeking is not only reading HIS WORD, but also seeking HIM in prayer, having burning desire to know who HE is, and loving HIS WORD.
