Dear Friend, I pray for you in the Name of Jesus for boldness and confidence in this interview! I bind all fear by the Blood of Jesus! Fear is NOT of God. You know where it comes from. "God has not given us the spirit of fear, but of love, power, and of a sound mind." 2 Timothy 1:7 You already have the experience needed here and you know how to get along with these kids. Now, that is the majority of the battle! Go over the books you use and review the CONTENT so that you feel confident to teach it. Some people are naturals at teaching and you sound like one of those. Have confidence in God to help you everyday. Make lesson plans, list the steps on the board, or do whatever helps you each day. God bless you dear and I know that He will bless your teaching and these kids if you will trust Him.
