This cross necklace has a real mustard seed inside. It's a fitting reminder of Jesus' words in Matthew 17:20 that faith as small as that seed can move huge mountains. Silver rimmed cross pendant is 5/8"; silver chain is 18". Gift boxed with our poem "The Mustard Seed." Text of poem: With faith there is so much that you can achieve, you can move mountains, if you first believe. Great things are possible when they first start with lots of prayer and faith in your heart. It takes just a little, in fact all you need is faith that's as small as a mustard seed. So please wear this necklace, and let your faith grow, by putting your trust in the God that you know. Poem copyright Dicksons, Inc.
