God's Will

Romans 12:2 KJV - And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what [is] that good, and acceptable, and perfect, will of God.

Is this passage teaching that we are to use our God-given faculty of discernment to determine ('prove') which of many options for God's will is the one that is good, acceptable and perfect in a particular situation?  Or, rather, is it that we are to have our mind so adjusted as to understand that God's will for us in any particular situation is in fact good, acceptable and perfect?  I think the latter.

The difficulty we face is acknowledging that anything contrary to our way of thinking and is burdensome to us might in fact be the good, acceptable and perfect will of God.  My will may be to take all steps necessary to alleviate a particular problem circumstance. Frankly, this is thinking that conforms to the world's way of thinking. God's will may be that I stay under that circumstance until He resolves it.  Which would be better?  My way or His?  His, no doubt.
