God created us with emotions because He delights in our worshipful appreciation of the beauty of who He is and how He will redeem. This means that, in the end, every emotion, even every dark one, is an opportunity to engage with Him and “pour out [our] heart[s] before him” as our act of trust (Ps. 62:8). He who invites you to approach Him boldly has promised to receive you tenderly, so cast your anxieties—and your guilts, joys, griefs, shames, and sorrows—on Him.
Put most simply: what you care about shapes what you feel. Emotions, you see, are designed by God to enhance truth and bring it to life.
