Assurance of having your prayer answered: Pray according to the will of God.
I John 5:14-15 And this is the confidence that we have in HIM (in God), that, if we ask any thing according to HIS will, HE heareth us:
15 And if we know that HE hear us, whatsoever we ask, we know that we have the petitions that we desired of HIM.
(Each of us must pray according to the will of God for our lives.)

Concerning a minister asking you to send your prayer requests to him:
James 5:16 The effectual fervent prayer of a righteous man availeth much.
effectual: according to the will of God for you
fervent: "red hot", intense
righteous man: a man who does scripture in his own life, following God in all things by the Holy Scriptures and the Holy Spirit

James 1:5 If any of you lack wisdom, let him ask of God, that giveth to all liberally, and upbraideth not; and it shall be given him.

Matthew 4:8-10 The devil taketh HIM (Jesus) up into an exceeding high mountain, and sheweth HIM all the kingdoms of the world, and the glory of them;
9 And saith unto HIM, All these things will I give thee, if thou wilt fall down and worship me.(worship: obey)
10 Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and HIM only shalt thou serve.
