Keep looking at the Word of God. Keep trusting it. Speaking of itself it declares to be living and sharper than any two-edged sword with capability to judge the readers. The Bible is not a stuffed animal destined for shelf-space. It is the live puppy anticipating interaction.
Preach the Word. Teach the Word. Its power suffices. The Story does things to the hearts of hearers/readers because it lives and breathes hope, assurance, and direction. Trust it.
As preachers and teachers, worry less over your illustrations and your three or four points. Trust more His quickening power. God does something to hearts when we tell His story. Be as creative as you want in delivery, but foremost of all, be extremely Word confident. Life will happen as a result!
