1. Am I good enough to be a Christian?
Satan always tries to condemn and discourage us. A classic whisper of the devil's is to tell us we are not good enough to be Christians. Even non Christians will accuse us of being hypocrites. That is a lie of the devil - you are good enough but not in your own strength. In your own strength you are nothing but now Jesus is in you, you have overcome the world! That is quite a thought, isn't it? 1 John 5:4-5 tells us that an overcomer is one born of God. "Who is it that overcomes the world? Only he that believes that Jesus is the Son of God."
Once I asked the Lord, "What do you see in me?" He replied, "I don't see you, I see Jesus in you." Isn't that a comforting thought?
