1 Korintus 2:14

2:14 The unbeliever ¹  does not receive the things of the Spirit of God, for they are foolishness to him. And he cannot understand them, because they are spiritually discerned.

1 Korintus 10:20-21

10:20 No, I mean that what the pagans sacrifice ²  is to demons and not to God. I do not want you to be partners with demons. 10:21 You cannot drink the cup of the Lord and the cup of demons. You cannot take part in the table of the Lord and the table of demons.

1 Korintus 14:22

14:22 So then, tongues are a sign not for believers but for unbelievers. Prophecy, however, is not for unbelievers but for believers.

[2:14]  ¹ tn Grk “natural person.” Cf. BDAG 1100 s.v. ψυχικός a, “an unspiritual pers., one who merely functions bodily, without being touched by the Spirit of God.”

[10:20]  ² tn Grk “what they sacrifice”; the referent (the pagans) is clear from the context and has been specified in the translation for clarity.
