Never taken

As I continue to seek the Lord on this path to restore the joy of my salvation...today I was meditating on the Lord seeking Him and bringing those heavy burdens at His feet I was reminded that my salvation will never be taken from me!  As pain, suffering and disappointments in our lives rob us of joy we so desperately seek after an need.  Salvation is always and forever and it won't return void in anyway.  That what happened on the cross has been done as Jesus said "it is finished".  Victory. Freedom!
But why is it so hard to just be content and joyful in salvation, that it has been finished and I am free. I have so many theories but I don't want to get into that.
It's been very recent the Lord telling me focus on joy of my salvation.  But I feel that he was stirring something in my heart back in the fall when I served in our church's Introducing God course.  I was reminded of God's story and His plan and purpose of redemption.  Something that I had been thankful for but not living it.  I feel that we get in a state of our spiritual growth where we get a little distracted or maybe comfortable that we lose sight of what has been done for us already.  That His grace is enough.
Today I read a small book I have been using as decoration in my family room because it has beautiful pictures of crosses.  "The Cross"  by Max Lucado.   And this really spoke to me..."His final pain was for you.  His final passion was you.  Before he went to the cross, Jesus went to the Garden.  And when he spoke with his father you were in the prayer.....God could not turn his back on you.  he couldn't because he saw you  and one look at you was all it took to convince him.  Right there in the middle of a world that isn't fair.  he saw you cast into a river of life you did not request.  He saw you betrayed by those you love.  He saw you with a body that gets sick and a heart that grows weak....He saw you in your own Garden of Gethsemane-and he did not want you to be alone....On the eve of the cross, Jesus made the decision.  He would rather go to hell for you than heaven without you." 

Scripture:  Isaiah 12:2-4
² Surely God is my salvation;
   I will trust and not be afraid.
The LORD, the LORD himself, is my strength and my defense
   he has become my salvation.”
³ With joy you will draw water
  from the wells of salvation.
 ⁴ In that day you will say:
   “Give praise to the LORD, proclaim his name;
   make known among the nations what he has done,
   and proclaim that his name is exalted.
