People will then tell me, "But, God cares about all aspects of our lives, though."
My point is, I don't think you'd be thinking about those things if you truly had the mind of Christ. Your life has to be setup like Christ in order for you to ask what he'd do in a situation. That's why it sounds so silly to ask "W.W.J.D.?" about so many things... Because Jesus wouldn't even be in that situation!
What is the mind of Christ, then? Unfortunately, it's not as pretty as getting to live a safe, comfortable life. In order to be able to filer things through W.W.J.D., you need to be seeking the same mind as Christ -- otherwise you're just asking W.W.J.D. in situations Jesus wouldn't be in. How do you seek the same mind as Christ?
Philippians 2:1-11
So if there is any encouragement in Christ, any comfort from love, any participation in the Spirit, any affection and sympathy, complete my joy by being of the same mind, having the same love, being in full accord and of one mind. Do nothing from rivalry or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others. Have this mind among yourselves, which is yours in Christ Jesus, who, though he was in the form of God, did not count equality with God a thing to be grasped, but made himself nothing, taking the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross. Therefore God has highly exalted him and bestowed on him the name that is above every name, so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Final point: If you're on the broad path, the only answer you should be getting to "what would Jesus do?" is: "Sell all that you have and distribute to the poor, and you will have treasure in heaven; and come, follow Me."
