This whole chapter of Isaiah is full of God's extraordinary promises to His people.  He reminds them that He chose them, and called them from the farthest ends of the earth.  He declares us the descendants of His friend.  He promises to confound our enemies - and help us rise above them.  He promises to rescue us when we're destitute and needy.  

You might love ice-cream.  You might love summer.  You might love Batman.  But God doesn't stop with these sorts of love. His love is complete.  His love is a refuge.  His love is a real comfort and a source of peace.  

You might have had someone tell you that they love you - only to change their minds later on.  God has no ability to respond to us in this way. In this verse - He's telling His people that His love goes back hundreds of years - dozens of generations.  For us today - that's thousands of years and hundreds of generations.  

But we already know from the verses covered earlier in this first week of Lent that God's love for us goes right back to the beginning of time.  You have no power to change God's mind regarding His love for you.  His love for you is as fixed as the universe itself.
