In Isaiah 40:31 the prophet writes ” but those who hope in the LORD will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.
It is easy to become discouraged when we look at the things of this world. It seems that the wicked prosper while the righteous struggle. Evil appears to be winning the battle for hearts and souls while God’s Word is ridiculed and watered down by those seeking the acclaim of this world. Churches are no longer separate from this world but embrace it and seek the approval of man rather than God. It is no wonder that we hear more and more about ministers “burning out”. It is natural to burn out when the oil runs out. We are just the wick in the lantern. Without the Holy Spirit to fuel us we will burn out and darkness will overwhelm us. But those who “wait upon the Lord”, those who are flowing with the oil from Heaven will renew their strength.
When this world gets you down it is important to return to source of our salvation. Jesus told the woman at the well in John 4:14 “Whoever drinks of this water shall thirst again: But whoever drinks of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.” Jesus is the source of our life, our joy, our strength, and our help. When the world is pressing in and your strength is gone go to the well. Jesus is waiting for you.
The prophet Isaiah concludes this word with a bold statement declaring that those that put their hope in the Lord will do extraordinary things. To fully understand his declaration we have to review verse 28 where Isaiah gives this description of the nature of God:
God does not faints, even though he upholds all things by the word of his power (Heb. 1:3);
God does not grow weary, we do not have to worry about our Lord ever reaching the end of His strength. “He will not suffer thy foot to be moved: he that keeps thee will not slumber. Behold, he that keeps Israel shall neither slumber nor sleep. The Lord is thy keeper: the Lord is thy shade upon thy right hand,” (Psalm 121:3-5);
He possesses all knowledge – God Knows! His knowledge is beyond our human comprehension. Knowing the unfailing nature of God Isaiah then reminds us that God shares His power and strength with everyone that depends on Him. He gives power to the faint and strength to those that have no might. If you are struggling and you don’t know what to do Jesus stands with arms open wide and beckons all who are heavy laden to come unto him and He will give you rest.
