Answer to the question

Proverbs 12:22 Lying lips are abomination to the Lord: but they that deal truly are his delight.
You ask: Why are my prayers going unanswered? Why is it that I can't seem to get what I need or want?
Could it be the lies that you speak? Could it be the negative words that come from your mouth? Could it be that the only positive things that you share with other concern only yourself?
But your iniquities have separated between you and your God, and you sins have hide HIS face from you, that he will not hear. Isaiah 59:2
God can not answer pray that he can not hear. (Prayers are hindered by our own actions) Instead of praying for things, try repenting of your sins known and UNKNOWN, those you are aware you committed and those that you are UNSURE of. God does forgive all he ask.
