Who is to say we are not to live by our feelings?
I feel what I believe engenders feelings. If I'm feeling insecure at my job my faith brings me to my Father's assurance in Matthew 6:25 to 31.
If I can't sleep I'm made secure by the wisdom of Proverbs 3:24.
Everything we feel is wrapped in God's words of wisdom.
What better feeling than living eternally beloved and secure in Christ?
