Are we running after God's own heart? Not just by saying that we love Him and feeling the motions every once in a while; I really mean are we so in love with Him that our hearts burn for Him every waking moment? That the moment we hear something ill-spoken about Him, we actually cringe to the point of wanting to cry or feel anger?
Although I am not like Peter (yet), I know that I am close. I love God so much, my heart burns for Him. Literally. At times, my heart paces in adoration of Him. Thinking about Him puts the hugest smile on my face.
At the beginning of Jesus' ministry, He did not reveal that He was The Messiah, for the time was not right. So for Peter to get a true heart revelation of this, you know that he eagerly loved the Lord! Oh, how sweet the wonder!
