we cannot serve fully if we are not happy. In Ephesians 6, Apostle Paul encourage children to obey their parents, so they will have long life and do well. and encourage the parents not to be exaggerated parents, engaging their siblings to be more futile and demanding.
Apostle Paul also mention to serve our masters or boss as if we were serving God and not men. Because we are accountable for them and they are accountable for ours.
Reading the Book of Ephesians, Apostle Paul also urge every one to wear the helmet of salvation and that is thru the Word of God. We must have knowledge from God, we must have wisdom from God. How? Through acceptance of Jesus Christ, through our Faith. And how do we get the Faith, it comes by hearing the message and the message was heard thru Word of about Christ (Romans 10:17)
