Other religions, false religions, have tendencies to place protective/defensive power into trinkets. Such trinkets include symbolic jewelry, cards with photos of religious figures and/or statues. Followers of these religions are taught to carry these trinkets around with them, or display them in common places. Followers then turn to these trinkets, often in prayer, when they need help or strength to stand, as if the trinkets can somehow help or protect them. In doing so, they turn the trinkets into idols. Scripture refers to this as idolatry. And what does Scripture have to say about idolatry?
I am the Lord your God, who brought you out of the land of Egypt, out of the house of bondage. You shall have no other gods before Me. You shall not make for yourself a carved image--any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My commandments.
Exodus 20:2-6
Little children, keep yourselves from idols.
1 John 5:21
Therefore, my beloved, flee from idolatry.
1 Corinthians 10:14
And this list could go on and on and on and on and on.
