Feelings Vs. Faith

I am a very emotional person,  so I have to allow the Holy Spirit to keep my feelings in check and to not allow myself to be ruled by my emotions.
I love this quote: 
Elisabeth Elliot ~” If you dwell on your own feelings about things rather than dwelling on the faithfulness, the love, and the mercy of God, then you’re likely to have a terrible, horrible, no good, very bad day. Our feelings are very fleeting and ephemeral, aren’t they?
We can’t depend on them for five minutes at a time. But dwelling on the love, faithfulness, and mercy of God is always safe.”
