Preaching

As I sit in my pastor's office getting ready to preach before the church I have a feeling of inadequacy. I have been a believer for just over 4 years. I have grown in my understanding of the bible and about my savior. I still feel who am I to preach to anyone, I am a sinner worse than any. I need the power of God to speak through me. With out Him I am nothing, but a sinful man with sinful actions and desires. I pray the Lord would humble me and break me of my sinful ways and sinful desires. I need Him more than ever. Christ must increase and I must decrease. Show me the way Lord help sustain me and make me a powerful tool for your Kingdom.
