Do you know that there is a verse in Galatians that says that "the law is not of faith"? In Romans, it also says, "For if those who are of the law are heirs, faith is made void and the promise made of no effect". So clearly, there is no way that we can give people the law and yet expect them to have faith. The law will disqualify them from receiving any blessing from the Lord. It is only faith in His grace that will qualify God's people and cause them to have great faith to receive what they need from the Lord.
When you come under grace and are delivered from the works of the law, faith will no longer be a struggle or barrier because you will walk with unconscious faith. You will not be wondering, "Do I have enough faith?" all the time, but you will see Jesus in His grace, and faith will just spring forth from the inside. It is that simple.
