Isaiah 40:31

Yet those who wait for the LORD Will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary.

The Christian walk is hard. It is not a sprint, but a marathon. When we first become a Christian, we start out on fire and excited to do the work of the Lord. We feel like we can do anything. And then discouragement starts to creep in. It could be from anywhere. Things start falling apart in the church around us. A role model that we looked up to deserts the faith. We fall back into past sins, allowing them to entangle us. When these things happen in our lives, it is easy for us to be discouraged.

What we need to do instead of allowing ourselves to be discouraged is return to the Lord. He needs to be our focus. If we think about Him and His greatness, we will gain new strength. We need to be diligent in following His word, no matter how hard it is. When we focus on God, rather than on ourselves or on others, it is much easier to be positive. We gain our strength, not by outside circumstance, but instead on our relationship with our Father.

Also, it helps to read a few verses before where it talks about the fact that the Lord does not grow tired or weary. This can be of great help to us, because God wants us to cast our burdens on Him. With other people, we might be afraid to turn everything over to them, but with God, we know we can because He can handle it. Giving God your burden is like lifting weights with a spotter. When we cannot do it anymore, we can leave it in His hands. In doing so, it becomes far easier for us to walk our Christian walk. If we will only wait upon Him, He can give us His strength to rely upon.

Yet those who wait for the LORD Will gain new strength; They will mount up with wings like eagles, They will run and not get tired, They will walk and not become weary.
