Pastoral wisdom here from Jon Bloom, Don't Follow Your Heart:

God designed your emotions to be gauges, not guides. They’re meant to report to you, not rule you. The pattern of your emotions (not every caffeine-induced or sleep-deprived one!) will give you a reading on where your hope is, because they are wired into what you believe and value—and how much.

That’s why emotions such as delight (Ps 37:4), affection (Rom 12:10), fear (Luke 12:5), anger (Ps 37:8) and joy (Ps 5:11) are so important in the Bible. They reveal what your heart loves, trusts, and fears. At Desiring God we like to say, “Pleasure is the measure of your treasure,” because the emotion of pleasure is a gauge that tells you what you love ...

Your emotions are gauges, not guides. Let them tell you where the attack is being made so you can fight it with the right promises.
