Delight in divine service is a token of acceptance. Those who serve God with a sad countenance, because they do what is unpleasant to them, are not serving Him at all; they bring the form of homage, but the life is absent. Our God requires no slaves to grace His throne; He is the Lord of the empire of love, and would have His servants dressed in the livery of joy. The angels of God serve Him with songs, not with groans; a murmur or a sigh would be a mutiny in their ranks. That obedience which is not voluntary is disobedience, for the Lord looketh at the heart, and if He seeth that we serve Him from force, and not because we love Him, He will reject our offering. Service coupled with cheerfulness is heart-service, and therefore true. Take away joyful willingness from the Christian, and you have removed the test of his sincerity. Cheerfulness is the support of our strength; in the joy of the Lord are we strong. It acts as the remover of difficulties. It is to our service what oil is to the wheels of a railway carriage. Without oil the axle soon grows hot, and accidents occur; and if there be not a holy cheerfulness to oil our wheels, our spirits will be clogged with weariness. The man who is cheerful in his service of God, proves that obedience is his element.
