Hope and Fear in Worship

وَمِنْ ءَايَـٰتِهِۦ يُرِيكُمُ ٱلْبَرْقَ خَوْفًا وَطَمَعًا وَيُنَزِّلُ مِنَ ٱلسَّمَآءِ مَآءً فَيُحْىِۦ بِهِ ٱلْأَرْضَ بَعْدَ مَوْتِهَآ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَعْقِلُونَ

And of His signs is [that] He shows you the lightning [causing] fear and aspiration, and He sends down rain from the sky by which He brings to life the earth after its lifelessness. Indeed in that are signs for a people who use reason.
