“The LORD will give strength unto his people; the LORD will bless his people with peace” (Psalm 29:11). When your heart is fully persuaded, you believe what God says. “The Lord is my strength.” Here the Lord will give strength. You need strength, you believe, and the Lord will give you strength.
Notice this is a promise. The Lord “will.” If you need physical strength today, then believe He will give it to you. Say it aloud, “Lord, I believe you will give me strength today.” Just believe that verse is as true as you have life. In fact, David says in Psalm 27:1 “the LORD is the strength of my life.”
Maybe you need strength to face a problem today. The Lord is your strength. He is your defense, your rock, and your fortress. He is with you every moment of every day. He is in you and He is your strength.
