When we find ourselves feeling anxious, that feeling tells us that something we treasure is being threatened…. [It is] a signpost telling us that something is amiss with our hearts. We are not loving the Lord as we should – which is to say, we have lost sight of his supreme loveliness and forgotten that in his presence only is fullness of joy (Ps. 16:11). We have other gods…. Our Savior, the one who loves and welcomes us, tells us where our treasure should be: with his kingdom and his righteousness (Matt. 6:33). If our treasure is in living our lives for him and in leaving our success and security to his providential care, and if our treasure is his righteousness, not ours, then we will be able to appreciate all the good things he bestows without succumbing to worry. On the other hand, when we find ourselves plagued by anxieties, we have to conclude that his kingdom and his righteousness are not the chief delight of our heart.
