'Now faith is the substance of things hoped for and the evidence of things not seen' Heb 11:1. Brethren Faith is the stance we take when the word of God comes. 'sub' means we are below him. Now if we trust on God, believe and be patient on His word, we are taking a step of faith. Things that can hinder your prayers.

1. You have to pray according to his will
   'For this is the confidence that we have in Him, when we pray according to His will, He answers us'
   Now some of us don't know the will of God towards our life. You're praying for a car. the question is: Does God want you to have a car at that particular time?

So if we pray according to His will, He more than faithful to answer.
