In our spirit we have 5 senses as well as 5 senses in our soul and body.

Our spirit man knows what to do.

1 Chron. 12:32a And of the children of Issachar, which were men that had understanding of the times,  to know what to do

(1Ch 12:32)  From Issachar's descendants there were 200 leaders who understood the times and knew what Israel should do. Their relatives were under their command.

But solid food is for fullgrown men, even those who by reason of use have their  (spiritual) senses exercised to discern good and evil" (Heb. 5:14).

"O taste and see that the Lord is good: blessed is the man that trusteth in Him" (Psalm 34:8).

Frequently, Scripture uses our five physical senses in a figurative way to help us comprehend our interaction with the heavenly realm of God's presence and power.

Spiritual Seeing

We can "see," for example, with spiritual eyes. Paul prayed thus for the believer: "The eyes of your understanding being enlightened; that ye may know what is the hope of His calling, and what the riches of the glory of His inheritance in the saints" (Ephesians 1:18).

Spiritual Hearing

Similarly, we are privileged to hear the voice of the Lord with spiritual ears. "My sheep hear my voice, and I know them, and they follow me" (John 10:27). "A stranger will they not follow, . . . for they know not the voice of strangers" (John 10:5).

Spiritual Feeling/Knowing

The sense of touch is the sense of feeling, and God can both touch and be touched. We read, for example, of "a band of men, whose hearts God had touched" (I Samuel 10:26). Of Jesus Christ, it is said that He is not a remote deity "which cannot be touched with the feeling of our infirmities" (Hebrews 4:15). Even people who never knew Him can perhaps "feel after Him, and find Him" (Acts 17:27) if they truly desire His great salvation.

Spiritual Smell &Taste

We can even become "unto God a sweet savor of Christ" (II Corinthians 2:15). To the world, the faithful Christian life and testimony can either be "the savor of death unto death" to those who refuse it, or "the savor of life unto life" (II Corinthians 2:16).

Finally, we are exhorted actually to taste the Lord, and see that He is good! His Word will be, according to our needs, either "sincere milk" (I Peter 2:2), "strong meat" (Hebrews 5:14), or "sweeter also than honey and the honeycomb" (Psalm 19:10). HMM

Our spiritual senses in tune with Holy Spirit knows what to do. It's called wisdom.
