First, without faith it is impossible to please God. You must believe deep in your spirit what you are speaking and know the heart of God. You must seek His kingdom first. Repent of all your sins and truly follow Jesus. You must live holy and only then you will receive God's promises in the Bible. You can quote/speak/affirm etc. bible verses a million times but if it's not from your heart and without faith, it is useless.

Also, satan answers some affirmations that is not of God and he also answers some of prayer requests especially if it is not deep rooted from the Holy Spirit.
