No so-called "good luck charms" or any other objects have the ability to change anything, no matter what some people claim about them.
You see, such ideas are based only on empty hopes or unfounded superstition, and frankly, you'd be better off saving your money. They also could entice you into occult practices that do not come from God, and will instead lead you away from Him. The Bible bluntly says, "I am against your magic charms" (Ezekiel 13:20).
Instead, I urge you to put your faith and trust in the living God. Only God knows all about you, and only He knows what is best for you. Why trust anyone or anything else? Furthermore, He loves you and He wants you to bring every problem and every concern you have to Him. The Bible tells us to turn to God and "Cast all your anxiety on him because he cares for you" (1 Peter 5:7).
Begin by turning to Christ, confessing your sins to Him and by faith asking Him to come into your heart and life. Then ask Him to lead you to a church where you can learn how to live from His Word, the Bible. No, I can't promise all your problems will suddenly vanish, but with Christ in your heart you will not face them alone–and He will help you and give you wisdom.
