‘Stand firm then, with the belt of truth buckled round your waist,’ Ephesians 6.14
The reason you need to fix truth around you is that it is so easy to live according to feelings, which can be very at odds with the truth of God. To live your life according to your feelings is to allow yourself to be blown and buffeted by anything that comes your way, so that every negative thought or painful memory is likely to drag you down. However, there is another way to live where you are not bound to follow your feelings. God has given you a belt of truth to put around you – another way to live.
All that God has revealed about himself and us in the Bible is the truth. It is the revelation that he loves you with a love so strong that it caused him to give the most precious thing he had for you – Jesus; that you are his beloved child, who is in a daily relationship with him; and that he is as close to you as the air you breathe and will never move away.
Take a moment to focus on each of these, and put on this belt of truth before you do anything else.
