"'To hope to do better is to fail to see yourself in Christ only.' You say, 'I hope to do better.' You know you're not. You need to see yourself in Christ today and realise that only the Spirit of God moving through you can accomplish this. And then Newell says again, 'To be disappointed with yourself means you believed in yourself.' Somebody says, 'Oh, I'm so disappointed in myself.' Well, you had better be disappointed in yourself. You know no good thing is going to come out of the flesh, friend. Stop believing in yourself, and believe that the Spirit of God today can enable you through the new nature to live for God. Also Newell says, 'To be discouraged is unbelief.' My friend, that means you don't believe God. God has a purpose and a plan, a blessing for you. And you need to lay hold of it. Here is another statement: 'To be proud is to be blind.' We have no standing before God in ourselves. Oh, my friend, see yourself as God sees you. Here is the final gem: 'The lack of divine blessing comes from unbelief, not a failure of devotion.'...My friend, the lack of divine blessing comes because we do not believe God it is not because of a lack of devotion. Oh, to believe God today!" (McGee J Vernon. Thru the Bible with J. Vernon McGee, Volume 4. Thomas Nelson, Inc, 1981. pages 698-699)
Why should a believer in Jesus Christ be beating themselves up with self-condemnation when there is now no condemnation for those who are in Christ? So you have failed! The Bible tells us all have sinned, and that includes me and you. Our call as failures and sinners is to humble ourselves, repent of our sin, and do what pleases God. Feelings of disappointment and discouragement are indications our expectations have not been met, our will has not been done, that we have put our trust in ourselves or something that is not God. As long as we rely upon ourselves and hold our belief we are able to do what only God can do, the cycle of disappointment will be perpetual. Believing our old man has died with Christ and we have been raised to new life in Jesus Who lives forever, the shield of faith extinguishes the fiery darts Satan or people throw at us. When we see ourselves in Christ because it is Gospel truth, through God's eyes it changes the way we see everything.
