Have you ever been jealous at all the success you see unbelievers have that you don't? Have you ever thought, why do they get blessed even though they don't serve the Lord? After thinking like that do you ever just ask God why them and not you? I'm so guilty of this, I do this all the time. Is this wrong? I don't have the authority to say if this is right or wrong but I want to share with you how I view this. I believe that there is a fine line that we can walk in this area that could make this right or wrong. I don't believe it's wrong to want some of those blessings that people around you get. What I mean by that is wanting to have a house of your own, a wife/husband, maybe even a better job, I believe is ok. Where we can go wrong is when we start to harbor bitterness and envy. I'll share an example with you that I've asked the Lord to help me with. I have a  friend who doesn't serve the Lord and just live life the way they want to. This friend has things that are desires of my heart. My friend is married, has a family, and has a brand new house. As I saw all these things just falling into place for my friend I started to get bitter and upset and I started to ask the question why him and not me? As I started thinking like this I started to get convicted and thought to myself is this how Jesus would love my friend? Then I thought to myself, instead of being jealous of the blessings that my friend received I should pray for the Lord to continue to bless my friend. How selfish is it to only pray blessings for someone when they are less fortunate then you?
What the Lord spoke to me in this area of my life is what Solomon wrote in Proverbs 23:17-18:
¹⁷ Do not let your heart envy sinners,
   but always be zealous for the fear of the LORD.
¹⁸ There is surely a future hope for you,
   and your hope will not be cut off.
Instead of being jealous of my friend I need to focus on the Lord and grab a hold of the fact that I have a hope that will not be cut off. I'm not saying that since my friend doesn't serve the Lord that everything he has is going to be taken away, but unlike my friend my hope is in Jesus and with that comes a future of joy that nothing could ever take away. These things that we desire like marriage, family, and jobs, even though are good things they are just temporal and not eternal. I'm not saying that we shouldn't want or strive to get those things but I'm just saying that they aren't the end all be all. Unless Jesus is the center of our lives these things that our hearts desire will never be enough.  
My prayer for us today is that we wouldn't allow bitterness or anger to fill our hearts in this area. I pray that the Lord would replace those feelings and thoughts with his love. I pray that we wouldn't be so consumed with the desires of our hearts and that Jesus would be our main desire. I pray for strength and faith for us to continue to let God be God.
