Food for Thought: A Devotional on God’s Strength

“The Lord is my strength and my shield; my heart trusts in Him, and He helps me. My heart leaps for joy, and with my song I praise Him.” – Psalm 28:7 (NIV)

Life can be full of unexpected challenges—moments when we feel like we don’t have the strength to keep going. But the good news? We don’t have to rely on our own strength. The Lord is our strength and our shield. When we put our trust in Him, He lifts us up, fills us with joy, and carries us through.

If you’re feeling overwhelmed today, take a deep breath and remind yourself that God is your strength. You don’t have to do it all on your own. Lean into Him, and He will help you.

How to Make Big Mac Fries Casserole

3. In a small bowl, whisk together all the Big Mac sauce ingredients until smooth.
   
4. Layer the crispy fries in a greased 9×13-inch baking dish. Top with the cooked beef mixture, and sprinkle shredded cheddar cheese evenly over the top.
   
5. Place the casserole back in the oven for 5 minutes until the cheese is melted. Remove from the oven, then top with shredded lettuce, chopped pickles, and a generous drizzle of the Big Mac sauce.
