Since, then, you have been raised with Christ, set your hearts on things above, where Christ is, seated at the right hand of God. Colossians 3:1
When overwhelmed by trouble, learn to free your heart. Even if you are suffering from the most dreadful illness, when you can hardly stand it anymore, even if you spend the whole day praying and sighing, free your heart. Chase your illness out of your heart. Set your heart on things above and see to it that God reigns in your heart. You can carry your sickness in a bundle on your back if you like, but it does not belong in your heart. Free your heart, I say. Cast out your misery from your heart, and bear your cross.
Let us not be impressed by sickness. For what is sickness anyway? If we live in an atmosphere of life, sickness is dispelled like a mist. We experience this, time and again, and so do doctors. Our mortal mists are not as dense as they seem at first sight. They dissolve. At some point they are there, then they disappear, and no one can tell where they came from or where they have gone.
So free your heart. Let your head be concerned with trifles, if you like, but God the Savior must be in your heart. Don’t let yourself be so hounded by trivialities that you are of no use anymore. Scores of people are paralyzed because they allow so many little things, especially their aches and pains, to enter their hearts.
Keep yourself free so that even in the deepest suffering, in the most unhappy of circumstances, in short, in all situations, you can joyfully serve Christ. Let nothing cloud your heart, least of all yourself – thinking and worrying about yourself. Instead, sacrifice yourself anew to God with prayer and thanksgiving. In this way you will give God the glory on earth, and he will lift you above all that presses down upon you.
