Ephesians 6:17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God.
You release your faith when you apply the Scripture that covers the problem. Expect the power of the Lord to do the same thing for you that was done in the Bible. When you look for Scriptures to cover the problems you are facing, you will build up a good list to work from. Eventually this habit will become second nature to you, as you apply them.
Expect God to honor your faith just as He has honored the faith of countless others in every century. First of all find out what the will of the Lord is concerning your need. Next, look for Scripture that matches your problem. Tell the Lord that a precedent was set there, and that you would like Him to do the same thing for you. It is necessary to get rid of any spirits of doubt or unbelief that may be affecting you.
