In Mark 4:40 and Matthew 8:26 fear/deilos is compared to faith:

>"He said to them, 'Why are you so afraid? Have you still no faith'" Mark 8:26 ESV

>"And he said to them, 'Why are you afraid, O you of little faith?' Matthew 8:26

In 1 John 4:18 fear/phobos [very similar] is seen in relation to love:

>"There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love."1 John 4:18 [perfect-teteleiotai]

Sin is punished on "the day of judgement" 1 John 4:17. Something to be feared.

Perfect love. Love reaches a teleological end in this world when it drives out fear. It does so by replacing it with:

 >"the love that God has for us".1 John 4:16
