Isaiah 40:29: He giveth power to the faint; and to them that have no might he increaseth strength. (KJV).
God loves to care and protect His children always. He empowers those who are weak or those who seemingly faint when they feel that they are not able to keep their trust or faith in God. God’s power makes the weak strong. He increases strength to those who have no might.
Many times we faint or become weak when faced with hardships. The enemy of our souls attacks our mind and says that it’s useless to trust God for unanswered prayers. The enemy tries his best to discourage us or demotivate us. He will try and question our faith in God, but when we look unto God for our spiritual strength through reading His word and by talking to Him, He will empower us and make us stronger. His grace is sufficient for us because we are made strong in our weakness. Our God will strengthen us to pull down every strongholds from our mind. When we think that we are weak, God will say to us that we are strong because He is stronger and greater. Greater is He who lives in us than he that is in the world. Look unto God when you are discouraged, disappointed, etc. Draw your strength from Him. Become stronger and stronger in the Lord every day.
Confess or speak out loud to yourself everyday that you are strong in the Lord and not a weak or a useless person. You are created with a purpose. You will run and not grow weary, you will walk and not grow faint.
