Observation: Jesus uses this request to launch into teaching about worldly possessions and wealth - warning about greed and hording, advising us not to worry about possessions since God loves us and will provide for us, and teaching about how to store your treasures in heaven, where your heart should be also. However, his first reaction here is instructive.
The person (a believer) in the crowd has asked Jesus to have his brother (a non-believer?) to share their family wealth. And Jesus answers ...
"No."
Application: Of all the challenges Christians face when it come to evangelism, the hardest is the perceived hypocrisy non-believers see in us. I believe one of the worst manifestations of this is the "prosperity gospel" message - when some preachers' teaching goes beyond "God provides" and into the realm of "since God provides, and God does what you faithfully ask, if you believe and are faithful and ask God for abundance God provides it, so if you don't have abundance you, you are clearly less faithful."
This is %&!#$&!%. Says who? Jesus says, right here. Yes, God provides!!!! He cares for us so much that we should never worry about that provision as he will always take care of us! But that doesn't mean he's going to make us rich, or even make us comfortable.
Ask Jesus for what seems like just a fair amount of money? NO! Why do you think Jesus should tell your brother to give you money?!?
God will take care of me. He may someday give me more if I am faithful with a little. He may take everything away from me to teach me that I can do all things through Christ who strengthens me! Both teachings are true, and both increase and decrease are the result of faith. When he gives to me, it may increase my bank account, but only if my bank account is needed to serve him greater - if he is preparing HIS resources for a work to come. If God's will can best be accomplished by making me poor, he will make me poor.
Anyone who say God will give you more if you are more faithful is at best misunderstanding the context of the gospel, at worst trying to pull a fast one, and in all cases negatively affecting our mission to reach others for Christ.
Prayer: Lord, I know you provide for me FAR beyond what I need. Please, never let me withhold any of it from you, and do not let it get in the way of any effort to reach others.
