In the sestet from sonnet xix by john milton, how is the idea of service to god interpreted?

That murmur, soon replies, “God doth not need 
Either man’s work or his own gifts; who best 
Bear his mild yoke, they serve him best. His state 
Is kingly. Thousands at his bidding speed 
And post o’er land and ocean without rest: 
They also serve who only stand and wait.” 

Rather than demanding work, God asks only for faith, devotion, or acceptance. 

If this is a true or false question i would say true
