The Ministry-to-Children website offers several free sermons for kids, including a salvation object lesson and a sermon about creation. This site provides a printable document for each sermon, and offers detailed instructions on the effective use of visual aids.
There are several other websites that provide sermons directed toward children, such as Sermons4Kids. This site offers a drop-down menu to select from among several sermon options, including Old Testament, New Testament and holidays and special occasions. Each sermon provides a theme, lists an object to use for sermon enhancement, and states what scripture the lesson is based on. Children's Sermons Online also gives a choice of several sermons for kids.
