I don't know how to answer that question because I cannot fully understand the heart of God. But, looking carefully at the evidence in Scripture, I notice that Jesus taught about money often in His parables and sermons. Paul had a lot to say about money too. Proverbs is full of wisdom for handling money.
God may not care a lot about money. After all, everything belongs to Him! He doesn't need money or anything money can buy. But, He certainly cares about how people He handle their money. The Lord cares about how men, woman and children feel about money.
"No servant can be devoted to two masters. Either he will hate the one and be devoted to the other; or he will be devoted to the one and despise the other. You cannot serve both God and money, (Luke 16:13 NIV (c)1979).
God cares who we are serving. Are we devoting our energy, time, and ambition to making lots of money or having an expensive lifestyle? Or, are we seeking after God and His Kingdom with every bit of strength we possess.
Money is a distraction for many Christians, keeping them from fulfilling their God-given destiny. Instead of walking in God's call on her life, the carnal Christian is distracted by cares of the world. Many times worries make us seek after money instead of Jesus.
