The Bible reminds us that prayer is not complicated. When we pray according to God’s will, we can have confidence that He hears us and answers.

I John 5:14-15 (KJV):

And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: 

And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
