Living Springs Q&a

Q&A #176 Matthew 10:42, struggling with anxiety. 1. In Matthew 10:42 he promises that of we give a cup of cold water, we will not lose our reward. What is the reward spoken of here? Eternal salvation or something else? 2. I struggle a lot with anxiety and I try submitting my fears to God. I have tried a lot of methods to help with anxiety but still feel swallowed up by it so often. Any thoughts on how I can live out Matthew 10:31 and other verses that tell us to fear not?
