The word of God teaches that there are some conditions for finding success in prayer:

1. And if my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways, then will I hear from heaven, and will forgive their sin, and will heal their Earth.

2 Chronicles 7:14

Repentance is a change of attitude, direction. When we understand that we are wrong, we go in the opposite direction of error.

2. And ye shall seek me, and find me, when ye shall seek me with all your heart.

Jeremiah 29:13

Sincerity in the search, when we put all our heart into our requests.

3. Therefore I say to you, whatever things you ask in prayer, believe that you receive them, and you will have them.

Mark 11:24

Faith

4. Confess your faults to one another, and pray for one another, that you may be healed. The prayer made by a righteous man can do much in its effects.

James 5:16

Justice

5. And whatever we ask of him, we will receive from him, because we keep his commandments, and do what is pleasing in his sight.

1 John 3:22
