'Spiritual' in the Bible

For I long to see you, so that I may impart to you some spiritual gift to strengthen you,

For we know that the law is spiritual -- but I am unspiritual, sold into slavery to sin.

For they were pleased to do this, and indeed they are indebted to the Jerusalem saints. For if the Gentiles have shared in their spiritual things, they are obligated also to minister to them in material things.
