Htiaf-The Poem Riddles Volume 4

If you have me you shouldn't worry; You can't earn me and you can't buy me, but you can trust in me and live by me; If you have me no matter how bad the situation is you know its gonna be alright; If you know me then I know you, If you've showed me then I've showed you too; I am more than a word, I am the very essence of a belief; If you have me in Christ, you will have eternal life; I am immpossible to see, yet if you have me, you trust me; You can't trick me or lie to me, for I can only be if you try me; People say they have me, but when trouble comes they deny me; If you truly know me, then your prayers will surely be answered; What am I? I am Faith!
