I’ve found in my years as a pastor that if Satan can’t get you to be bad, he’ll get you to be busy.

And this causes us more stress than we can imagine. In the last few days, I’ve been sharing with you seven principles of stress-free living from the life of Jesus.

The first three principles were:

1. Identification: Know who you are
2. Motivation: Know whose approval you are living for
3. Vocation: Know your calling

Jesus’ fourth principle of stress-free living is concentration. You must know what matters most.

Jesus was a master of concentration. He focused like a laser on what the Father wanted him to do.

When light is diffused, it has no power at all. But light that’s focused has enormous power. Take the sun as an example. On its own, the light won’t harm grass. But if you focus its light with a magnifying glass, you can burn that grass.

Focus light even more and it becomes a laser—and a laser can cut through steel and kill cancer.

If you want your life to matter, focus it.

Jesus showed us this in Luke 9:51: “As the time drew near for his return to heaven, he moved steadily onward toward Jerusalem with an iron will” (TLB).

Jerusalem was where the cross was. Jesus knew that was where God wanted him. Nothing would keep him from it.

You have enormous spiritual power that will only be unlocked if you decide what’s most important to you. You can focus on either what will last for eternity or what is temporary. It’s your choice.

Paul tells us in 1 Corinthians 10:23, “Someone may say, ‘I’m allowed to do anything,’ but not everything is helpful. I’m allowed to do anything, but not everything encourages growth” (GW).

You’re free to do anything, but not everything will be helpful. If you don’t concentrate your life on what matters most, you’ll stress yourself out over what matters least.
