What would Jesus do? Or what is Jesus doing? Both good questions. But, for me, the second is more important than the first.
It really comes down to whether you live your life by 'quandary ethics' ie trying to decide what the right thing to do is on each separate difficult occasion. Or whether you focus on building 'character' so that you automatically do the right thing.
I wd argue that sticking close to Jesus, observing what He is doing day by day in everything, even little things, means that we grow in His likeness becoming more generous, courageous, tolerant, self controlled, loving etc. Then, when a 'difficult situation' arises, we will naturally respond the way Jesus would because we have grown in the character of Jesus.
Think for example of a situation where you are asked to give for some worthy cause. You might deliberate on whether this is best use of yr spare cash, how much you shd give, you might ask WWJD? Ultimately you might give and this would be an act of generosity but not the act of a generous person. The generous person would already have given. That's just the way he is.
