Yes, of course God wants you to provide for your family; He gave them to you, and you have a God-given responsibility to do all you can to provide for their needs. The Bible urges everyone "to devote themselves to doing what is good, in order that they may provide for urgent needs" (Titus 3:14).
But God also doesn't want us to constantly worry about money or make it the most important thing in life. When that happens, money becomes our master instead of our servant -- and before we know it, other things get crowded out. In our frantic search for financial security we end up ignoring the needs of others, and sacrificing time with our families and friends.
Most of all, we lose sight of God and our need to trust Him. We think everything depends on us, and we lose sight of our dependence on Him. What others think of us becomes more important than what God thinks of us, and we forget that everything we are and everything we have comes from Him. No wonder the Bible warns that "The love of money is a root of all kinds of evil" (1 Timothy 6:10).
Has this happened to you? Stop and evaluate your life -- and then open your heart and mind to Christ, and make Him the foundation of your life and your family. Then be grateful to God for all He's given you, and ask Him to help you use your money wisely, and for His glory.
