But they that wait upon the Lordshall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint. (Isaiah 40:31 King James Version)
God gives strength to those who depend on Him. When we put our confidence in God, he'll give us the hope we need to make it through. We have to wait on God. Everything God has in store for us is in his right timing. It may seem like we can't make it through or God has forgotten about us, but He hasn't! He's here with us all the time and understand what we're going through.
He'll give us the strength we need daily so we won't grow tired of waiting. Wait on the Lord and be of good courage.
