Sometimes our thoughts can get on a bus going the wrong direction, away from the truth and away from peace. We have to choose to stop the bus, get off, and get on the bus going the opposite direction.
In Mark 5 we read the story of Jesus meeting Jairus. When his daughter dies, Jesus interrupts Jairus' thinking and tells him not to fear, and simply to trust him. Then Jesus raises his daughter from the dead!
2 Cor 10:5 we take every thought captive and make it obey Christ.
We can control our thinking, and choose what we focus on.
Thankfulness is a great way to stop our thought bus from focusing on the negative things, and turn our thinking around to focus on Jesus and his truth.
Jesus, when I start thinking negative and fearful thoughts, please interrupt me, like you did Jairus! Jesus what do you want to tell me about that situation?
Think of 3 things your are thankful for.
