Satan doesn't want you to know that the favor of God is upon you, that you've been blessed by Him and given all the good things you enjoy.  Actually he doesn't want you to think that God's done anything for you!  His lie is that you've no purpose, no power and no potential.  To convince you he'll play the race card.  If that doesn't work he'll play the childhood memories card.  Finally he'll resort to reminding you of all the broken promises and shattered dreams.  If you buy into it you'll have such low self esteem that you won't believe God has blessed you in any way, or that you have any real possibility for a successful life.

Understand this:  No matte how limited your ability or lack-luster your accomplishments are to date, you don't have a thing God didn't give you.  Your blessings have been made possible only because the Lord is on your side.  Listen: "By this I know thou favorest me, because mine enemy doth not triumph over me. " (PS 41:11-12

David understood that his enemies were attacking him because they could see the favor of God on his life.  Do you understand that too?  If you don't, you won't expect the attack,  understand the reason for the attack, or know how to respond to the attack.  You're blessed, that's why you are a target!  They're jealous because of what God has done for you.  How come they see it and you don't?
