God's greatness.(Isaiah 40)

In Isaiah 40 God is speaking to his prople a people privileged,blessed by God,loved by God,and yet a people who often lost sight of His uniqueness,and who would turn to other so called god's,made of stone,or wood.So in Isaiah 40 ,He  challenges them to look beyond their so called god's,to Him ,and his greatness ,in v10 He reminds them that He is the sovereeign God he declares His greatness and transcdence,in comparsion to their impermance v 7-8.As regards the nations they are nothing in comparsion to God v15-17.In verse 21ff God declares his incomparable greatness,in comparsion to  people who are likened unto grasshoppers,and earthly rulers  who are here today and gone tomorrow.He tells them to look up to the heavens and reminds that He created them.In v27 God poses a question as to what his people are saying ,that He really dosen't care for them or what was happening to them,one commentator describes what they are saying was a hideous lie. God is so great and awesome and does not grow tired or weary,He pays attention to those who need Him,if they wait on Him ,he will renew their strength,so much so that they will soar on wings like eagles; they will run and not grow weary,and they will walk and not faint.'
