Devotional feelings are pure ones consisting of sweetness and innocence. They are feelings of faith in God, but they can be shaken.
Faith, without some wisdom to back it up, may fail you in a moment of need. Both are needed for long-term spiritual attainment; like feeling close to God and close to others, too in an unshakeable way. Or having true feelings, no matter what, becoming spiritually accomplished.
If either faith or wisdom is lacking, your life cannot function right. It is like understanding your doctor’s prescription but somehow not trusting it anyway. It leaves you feeling unsure. So have a dialogue between your feelings and your understanding. They need to know each other and work together well!
