Most people are selfish and self-centered, focusing only on what benefits them. Such thinking claims that the more you have, the more you accumulate, and the more attention you receive, the happier you'll be.

Yet, most of the time, such selfishness only makes a person more depressed than ever. This is because when all you focus on is yourself, you'll always want more, and you'll never be satisfied with what you have. On the other hand, if you live focused on how you can bless others and serve them, then God will give you joy.

It is no surprise, therefore, that Jesus said, "It is more blessed to give than to receive" (Acts 20:35).

Likewise, in John 13:1-17 Jesus is seen washing his disciples' feet; he sets an example by humbly giving himself to his disciples. Then, in John 13:17, Jesus tells them, "Now that you know these things, you will be blessed if you do them." In other words, you will be blessed, which in the Greek has the meaning of being happy, if you give and serve others. The Bible makes it clear that joyful living requires giving.

We all have exactly 24 hours in one day. No more; no less. You will use that time on what you consider to be important.

No one else is forcing you to do anything. You only commit to things because you choose to; so, your schedule reveals your priorities. Examine your schedule, and you might be surprised when you discover what your priorities turn out to be.

Instead of scheduling your priorities around your life, you ought to schedule your life around your priorities.

What should those priorities be? In Matthew 6:33, Jesus says, "Seek first his kingdom and his righteousness, and all these things will be given to you as well." Of the Ten Commandments, the very first commandment God gave was: "You shall have no other gods before me." The Bible is clear: God should be our number one -- most important -- priority.

In John 15:1-4, Jesus talks about pruning off things that produce no fruit. That is, he tells us to cut off anything that does not have meaningful, eternal value, which means that we are to get rid of anything that doesn't further our relationship with God. Clearly, God doesn't want to be number ten on a list of top ten priorities. In fact, God really doesn't even want to be number one on a list of ten; God wants to be number one on a list of one!

You could spend or waste your time doing meaningless things; or you could invest your time in order to achieve maximum eternal impact.

When you seek God as the only thing you need, he will take care of everything else (see Matthew 6:33). In Luke 10:38-42, we learn the story of Mary and Martha. As Jesus and his disciples were on their way, he came to a village where a woman named Martha opened her home to him. She had a sister called Mary, who sat at the Lord's feet listening to what he said. But Martha was distracted by all the preparations that had to be made. She came to him and asked, "Lord, don't you care that my sister has left me to do the work by myself? Tell her to help me!" "Martha, Martha," the Lord answered, "you are worried and upset about many things, but only one thing is needed. Mary has chosen what is better, and it will not be taken away from her." That's what it means to seek the only meaningful, eternal thing -- God.

Therefore, prune your life. List practical ways that you can cut out the junk in your life in order to focus on knowing God better, seeking him and knowing his word and his truth. That's the only thing needed -- that's how you invest your time wisely.
