Jesus gives us these simple instructions concerning money and possessions: "Do not store up for yourselves treasures on earth, where moth and rust destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moth and rust do not destroy, and where thieves do not break in and steal." (Matthew 6:19-20)

He commands us not to store up money here on Earth, but instead to invest that money into heaven—into the Kingdom of God. Why is it so important to put your money into the Kingdom? Jesus explains: "For where your treasure is, there your heart will be also" (Matthew 6:21).

It is impossible to overlook the importance of that verse. Wherever your treasure is, that determines where your heart will be. Your money leads; your heart follows. Knowing this, Jesus commands us to put our money into eternal things. Why? So that our heart will be into eternal things.

For example, say you invest money into a company's stock. Previously, you didn't really care about that company, and you didn't bother to read news articles about them. Now, however, you're scouring the newspaper for any articles that even remotely relate to that company, you check their stock price daily, and you religiously read their earnings reports. What caused such a change? Your money went into the company and with it your heart.

This principle—where your money goes, your heart follows—is illustrated very well in Mark 10:17-22, which records the story of a rich young man who came to Jesus asking how to be saved. He had done everything right and followed all the laws and commandments, but, according to Jesus, there was "one thing" he lacked: "Go, sell everything you have and give to the poor, and you will have treasure in heaven. Then come, follow me." At this the man's face fell. He went away sad, because he had great wealth.

The man had great wealth, but really his wealth had him—it owned and controlled him. Jesus wanted the man's heart, and so Jesus demanded his money. Jesus knew that the man could never follow Him if his heart was more attached to his possessions than to God.

The man's face fell, and he went away sad because his heart was too attached to his possessions. His money was invested in his own possessions, and therefore his heart was invested in his own possessions. However, Jesus wanted to break that bondage, so he commanded the man to give away all of his possessions to others. By giving his money to help the poor and the needy, Jesus knew that the man's heart would be transformed into serving others, and in so doing he would come identify with and follow Christ.

Do you want your heart to be full of love for others? Give to them, and bless them with your money. Then your heart will follow.

If you want a heart for God, invest your money in building the Kingdom of God. Then your heart will follow. If you want a heart for the poor and the needy of the world, use your money to fight global poverty and hunger. Then your heart will follow. If you want a heart for global missions, support missionaries in Africa, Asia, and the rest of the world. Then your heart will follow. Wherever your treasure is, that's where your heart will be.

It's very tempting to think that happiness will come to me once I get something: "I would be happy if I just had a bigger house, another car, a better job, more money, a different wife, a nicer family, a new TV...." But such thoughts are very deceptive.

In truth, all those things we want actually make us miserable; we fight and quarrel about what we want, and then we're upset when we don't get it (see James 4:1-4). Don't get caught up in things that you want or need. Instead, you should not worry about getting what you need; rest assured your heavenly Father will take care of what you need (see Matthew 6:30-32).

It's foolish to make your enjoyment of life hinge upon anything. There will always be one more thing for you to acquire before you can "enjoy life." The more you have, the more you have to worry about, which makes life that much harder to enjoy.

Instead of expecting possessions or circumstances to give you joy, seek the only source of everlasting joy—Jesus. Jesus says he came to Earth "so that [you] may have the full measure of my joy within [you]" (John 17:13). Similarly, Jesus said, "I have told you this so that my joy may be in you and that your joy may be complete" (John 15:11).

Jesus offers to make our joy complete and to give us the full measure of his joy. Since Jesus is wholly God, His joy is complete and whole joy. That Jesus offers us such joy is astonishing.

Therefore, find your joy in God for in his presence is fullness of joy (see Psalm 16:11). Don't let your joy depend on getting all the things you want because there will always be more things that you don't have, and therefore there will always be more things that will prevent you from enjoying life. Let Jesus be your joy, rather than waiting to enjoy life "when...."
