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.
