Fear of God or Fearless?

सुणि भै बिनासे सगल नानक प्रभ पुरख करणैहारे ॥३॥
उपजिआ ततु गिआनु साहुरै पेईऐ इकु हरि बलि राम जीउ ॥

Suṇ bẖai binaasay sagal Nanak parabẖ purakẖ karṇaihaare. 

Upjeaa ṯaṯ gyaan sahurai paiye ik hari Bal Raam jio.

Meaning:

Hearing this - all my fears have been dispelled; O Nanak -(that) God is the Primal Being, the Lord - Creator and sustainer.

For the one - in whose heart the 'Brahm-Gyan' has appeared - this world and the next unseen, unknown world, both become the same. He is neither worried or afraid in this world nor about the next. 

ਸੁਣਿ ਭੈ ਬਿਨਾਸੇ ਸਗਲ ਨਾਨਕ ਪ੍ਰਭ ਪੁਰਖ ਕਰਣੈਹਾਰੇ ॥੩॥

ਉਪਜਿਆ ਤਤੁ ਗਿਆਨੁ ਸਾਹੁਰੈ ਪੇਈਐ ਇਕੁ ਹਰਿ ਬਲਿ ਰਾਮ ਜੀਉ ॥
