God is strong for the weak. He increases our strength when we need it. Many believers throughout history accomplished great things for God, and they will tell you it was only through the Lord's strength they did. God is our strength. When you feel weak, when you feel like you can't go on, when you don't think you can take another step, pray and ask God for His strength. Lean on Him.
My Prayer...
Thank you, God, for sustaining me and keeping my faith alive when I have been under attack from the Evil One and have grown weary with the challenges and hardships of life. Please give those I love, and mention now by name, the strength to press on even though they are weary and weak. Please be real in their lives and let them know that you are coming with grace to help and redeem as their Great Deliverer. In Jesus' name I ask it. Amen.
