But now stretch out your hand and strike everything he has, and he will surely curse you to your face
Job 1:11 (NIV)
One of the things I love about this verse is how Satan approaches God regarding Job's weakness. In his approach, he makes no reference to Job's faith, nor to his righteousness, nor even to his integrity. Furthermore, he would never do that because God Himself testified to him that there is no one like Job in all the earth. This comparison of God is directly related to Job's integrity.
Satan touches precisely what is at the very basis of man's weakness and pride, his possessions. The more we have, the more we want to have. This conversation between God and Satan, especially this verse, is not just for Job weakness but for all humanity. In this sense, if Satan were to question God about your faithfulness and integrity, wouldn't he mention this same weakness.
If possessions are not the most important thing to you, there is still something in your life that would make you doubt God if He took them away or acted contrary to your expectations. Something that would make you act just like Satan hoped Job would. My advice today, everything comes from God and everything is for Him. If you are alive, it is because of His grace. So don't give Satan any opportunity to find a reason to disapprove of you before God.
May the grace of God be with you all.
