Jesus says, in Matthew 6:24, No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money. Jesus is making the point that our heart's highest loyalty will be for only one thing. We can't be equally devoted to two things; ultimately one will win out over the other.

If money is the most important thing to you (i.e., if you're greedy), then you will serve your money more than you serve God. And you will find it very difficult to follow God's instructions to give to others: If there is a poor man among your brothers ... do not be hardhearted or tightfisted toward your poor brother. Rather be openhanded and freely lend him whatever he needs (Deuteronomy 15:7-8).

If it's true that no one can serve two masters, then the best way to fight against greed is to make sure that your master (your highest loyalty) is God—not money. Follow God above all else; that way your money will follow God, too.

John writes, If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? (1 John 3:17). That sounds rather harsh at first, but it's really no different than what Jesus said in Matthew 6:24. If you love your money more than God, then you'll keep your money for yourself rather than giving it away to help others. The only way you'll give generously to others is if you love God more than you love your money. So, how do you know if you love God more than money? By examining what you do with your money: Do you keep most of it, or give most of it?

If you want to fight against greed (that is, if you want to love God more than your money), then you'll follow God's instructions to give—give to the poor, give generously, give joyfully, give liberally, and give regularly. Giving is the best weapon against greed.

We all experience difficulties, problems, and trials throughout life. Usually, we also look for ways to solve those problems. All of the various solutions basically ask one of these two questions: "What can I do to solve this?" Or, "What can God do to solve this?"

In other words, we either try to solve the problem on our own, or we let God solve it. Obviously, it is much wiser to give your problems to God.

Therefore, in the midst of your problem, Trust in the LORD with all your heart and lean not on your own understanding (Proverbs 3:5). Trust God to solve your problems. Trust in the LORD forever, for the LORD, the LORD, is the Rock eternal (Isaiah 26:4).

During your trials you should frequently quote Psalm 91:2: I will say of the LORD, "He is my refuge and my fortress, my God, in whom I trust."

Furthermore, when you're truly trusting in God, there is nothing to worry about. Jesus said, "Do not let your hearts be troubled. Trust in God; trust also in me" (John 14:1).

Make this your cry: "Some trust in chariots and some in horses, but we trust in the name of the LORD our God" (Psalm 20:7).

Trust the Lord God Almighty in every area of your life, even during problems, because every problem gives you an opportunity to trust God.
