What the Bible say about unbelievers!

Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers. 1 Corinthians 14:22

Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness? 2 Corinthians 6:14

The wicked in his proud countenance does not seek God;God is in none of his thoughts." Psalm 10:4

Because of this, God gave them over to shameful lusts. Even their women exchanged natural relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their perversion.Romans 1: 26,27.
