Close to His heart

Isaiah 40:11 says, "He gathers the lambs in His arms and carries them close to His heart..."  That's where I want to live...close to the heart of my Father God.  I was thinking about this several weeks ago while I was holding my mom and dad's golden retriever puppy in my arms.  She snuggled up to me and put her head on my shoulder.  She was trusting, and peaceful, and she knew that she was safe in my arms.  She was content in my arms for about 20 minutes and then she started wiggling to get down.  When I set her on the ground, she took off running to see what was going on around her.
I am so much like a puppy when it comes to my relationship with God.  I love to be close to His heart and listening to what He has to say to me.  I love to feel the peace, and love, and joy that are in His presence.  But, for some reason, I think I need to wiggle out of His arms and check out what is happening in the world around me.  More often than not, my little sojourns leave me frustrated, insecure, and fearful.  Why would I want to leave God's loving arms?  I am struggling with that question.  It seems so simple, and yet, it is so hard for me to stay there.  I need to remember who God is and who I am.  He is the Good Shepherd and I am His little lamb.  Held in His arms and close to His heart is where I want to stay!
