There's a really common attitude in the church (and I know because I've held it) that says that if we're really godly and devoted to Jesus, God will give us the things that we want. We might not say, or think, that we “deserve” them (because we know it's all grace); but consciously or subconsciously, we believe that if we live a righteous, dedicated life, God will deliver them: a nice place to live, a job, a spouse, a baby, etc.
For my thoughts are not your thoughts,
neither are your ways my ways, declares the Lord.
For as the heavens are higher than the earth,
so are my ways higher than your ways
and my thoughts than your thoughts. (Isaiah 55:8-9)
I so easily fall into the trap of thinking that I can somehow manipulate God and force situations to turn out the way I want them to by doing the right thing. I am often under the illusion that if I fast enough, pray intensely enough or use the right words, come to the right point of surrender, or obey fully enough, then God will grant me what I want. The outcome will be good, and by good, I mean the way I want it to be.
