We don't just try faith. We're either in faith or we're not in faith. We either believe God or we don't believe God. There is the scripture concerning tithing that says test Me, prove Me and try Me in this and see if I won't do as I promise (paraphrased).
There are many "if you do this, then I'll do that..." conditional blessings God makes available for us to take advantage of. However, we cannot try the foundational truths of God. We're either saved or we're lost. We're either in faith or in fear. We either accept the grace or refuse it. There is no middle ground.
Let me ask you something. How are you judging your faith? Are you judging it on whether a storm came or not? Are you one who would say, "I believed God would take care of me. Then I went out and got in my car and the engine threw a rod. I guess faith just doesn't work..."?
Well, big deal! Your car throwing a rod has nothing to do with faith. Faith has to do with how you react when your car throws a rod. Faith has to do with whether you kick it and cuss and act like a fool.
Faith is when you say, "Father, in the name of Jesus, I ask for Your grace to get my transportation lined out. Thank You for giving me Your grace."
God will give you grace. Then you must believe He gave it to you. That's where faith comes in. He can give you the grace, but you will make the grace of no effect if you don't believe and walk in faith.
Some people say, "Well, I tried grace." Grace is not something you try. You accept it by faith.
