Assurance for Weary Israel

Isaiah 40:27-28

Why sayest thou, O Jacob? and speakest thou, O Israel? `My way hath been hid from Jehovah, And from my God my judgment passeth over.'

Hast thou not known? hast thou not heard? The God of the age--Jehovah, Preparer of the ends of the earth, Is not wearied nor fatigued, There is no searching of His understanding.
