These are complaints I hear a lot from Primary Song Leaders. Hence the cottage businesses that offer insta-print FLIP CHARTS and PICTURES for use in Primary. There is absolutely nothing wrong with using pre-prepared visual aids and teaching ideas, but what about the Song Leader's own EFFORT?
How do you expect success without putting forth EFFORT?
Why would teaching in Primary be any different?
Even if you use IDEAS and VISUAL AIDS created by other people, you still should put in the EFFORT to learn how to use them, memorize the songs, and connect with the children. You too can be successful if you put in the EFFORT!
