Can a boy who repented after unintentionally and inadvertently cursing God return to the straight path?

The scholars have unanimously agreed that cursing God is an act of disbelief and apostasy, and that the repentance of one who repents from this act is valid, due to the Almighty’s saying: "Say, 'O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.'" Therefore, whoever curses God must repent, feel remorse, adhere to God's commands, and increase in acts of obedience.
