'Possess' in the Bible
We also speak of these things, not in words taught or supplied by human wisdom, but in those taught by the Spirit, combining and interpreting spiritual thoughts with spiritual words [for those being guided by the Holy Spirit].
But I will come to you soon, if the Lord is willing, and I will find out not just the talk of these arrogant people, but [evaluate] their [spiritual] power [whether they live up to their own claims].
and those who weep, as though they did not weep; and those who rejoice, as though they did not rejoice; and those who buy, as though they did not possess [anything];
Now about food sacrificed to idols, we know that we all have knowledge [concerning this]. Knowledge [alone] makes [people self-righteously] arrogant, but love [that unselfishly seeks the best for others] builds up and encourages others to grow [in wisdom].
However, not all [believers] have this knowledge. But some, being accustomed [throughout their lives] to [thinking of] the idol until now [as real and living], still eat food as if it were sacrificed to an idol; and because their conscience is weak, it is defiled (guilty, ashamed).
Do all have gifts of healing? Do all speak with tongues? Do all interpret?
And if I have the gift of prophecy [and speak a new message from God to the people], and understand all mysteries, and [possess] all knowledge; and if I have all [sufficient] faith so that I can remove mountains, but do not have love [reaching out to others], I am nothing.
So it is with you, since you are so very eager to have spiritual gifts and manifestations of the Spirit, strive to excel in ways that will build up the church [spiritually].
