Joyful in grace and bounty from God and [joyful in knowing] that God does not let the wage of believers go to waste. The cause and reason for their being joyful is a bounty and grace from God. That is to say how would they be joyful if not for His grace and bounty to themḍ Their being joyful in grace is only because they are His servants and He is their protector. If not for His grace and favor to them they would not be in this state.
