Content, happy, strenuous, untiring
... just because we are not doing God’s work for Him, but He is doing His own work through us; just because we do what work He appoints to us; not we but He is responsible for the harvest. All that is required of stewards is that they be found faithful ... Let us then labour on in whatever sphere God gives it to us to labour, content, happy, strenuous, untiring, determined only to do God’s work in God’s way; not seeking to intrude into work to which He has not appointed us, and not repining because He has given us this work and not that. Each one to his own labour, and God the rewarder of all!
