Well, it actually depends…
It’s not ok if you’re discontented because you can’t seem to afford the iPhone 7, even if you currently have the iPhone 6s Plus, and especially if your discontent comes from envy because your colleague happens to have it. This is where discontentment becomes harmful: When you tend to spend unwisely because of your desire to acquire, causing you to being broke, in debt, and all the more discontented with your situation.
Being content with what you have is a blessing. And we only find this in a relationship with Jesus. In this relationship you find all you need and desire. First find your contentment in the presence of God.
Keep your life free from love of money, and be content with what you have, for he has said, “I will never leave you nor forsake you.” – Hebrews 13:5
But you can have a discontent for your salary if it comes from a desire to give more, to bless your loved ones and others. A healthy discontent is one that is never contented in his or her service or generosity toward others. It’s not the kind that keeps you up all night, but the kind that gets your day going and keeps you working with all your might. It’s doing your best for a greater purpose – to give more, to bless more.
So what should you do?
Work hard! Do your best. If you have this mindset, then you start working for that increase in your salary with a renewed purpose. True success is found in how much more you contribute, not in how much more you consume.
In all things I have shown you that by working hard in this way we must help the weak and remember the words of the Lord Jesus, how he himself said, “It is more blessed to give than to receive.” – Acts 20:35
