'Unspiritual' in the Bible

We know that the Law is spiritual, but I am a creature of the flesh [worldly, self-reliant—carnal and unspiritual], sold into slavery to sin [and serving under its control].

You are still worldly [controlled by ordinary impulses, the sinful capacity]. For as long as there is jealousy and strife and discord among you, are you not unspiritual, and are you not walking like ordinary men [unchanged by faith]?

Let no one defraud you of your prize [your freedom in Christ and your salvation] by insisting on mock humility and the worship of angels, going into detail about visions [he claims] he has seen [to justify his authority], puffed up [in conceit] by his unspiritual mind,

This [superficial] wisdom is not that which comes down from above, but is earthly (secular), natural (unspiritual), even demonic.
