As some bible expositor puts it - The smallest, commonest acts of daily life are truer worship than is rapt and solitary communion or united prayer, if the latter can only be secured by the neglect of the former. Better to be in the lower parts of the house attending to the humble duties of the slave than to be in the upper chamber, uniting with the saints in supplication and leaving tasks unperformed.
.. In the execution of duties, Paul admonishes Christian workers in Ephesians 6:5-8 be obedient to those who are your superiors with fear and trembling and with humility of heart as unto Christ; not with eye service, as men pleasers, but as servants of Christ, doing the will of God from the heart. With good will doing service as to the Lord, and not to men; knowing that whatever good anyone does, he will receive the same from the Lord, whether is a slave or a free born.
