It can be quite easy for us to say that we trust God, to think that we trust God. But how are we living that our in our actions? What impact is our trust in God having upon our lives? In the story of David and Goliath, David does not just say that he trusts God. His trust led him directly to action. He did not just think, well if I fought against Goliath, I am sure God would help me; he thought, God will help me so I will fight. This is a confident faith, a faith without doubts.
The size of our obstacle does not matter. Nothing that we can fear: no person, no situation, no conflict, no challenge is bigger than the God we believe in. Maybe you feel able to trust God in the small things, but struggle when that thing you are facing becomes bigger or more serious or scarier. Do not worry, you are not alone, but now it is time to grow your faith. Get to know the God we serve, remind yourself just how big he is, remind yourself that he has already won.
