It is both amazing and comforting that God thinks about us. His thoughts towards us are infinite, stretching back before the beginning of time. They are precious and gracious. They are also inescapable. There is no place we can go from his presence.
God is strong. Isaiah 40 gives us a glimpse of his unlimited strength and authority over the whole universe. The amazing truth at the end of the chapter, however, is that God shares this strength with the weak. He is caring in his strength. We too can receive this strength through faith as we wait on God.
