We, as born again believers, are called to be sons and daughters who are serving in the kingdom of God but at the same time friends of God. Malachi prophecies of our day, in the New Covenant, that God will treat us as sons who are serving Father (Malachi 3:17). Paul tells us in the New Covenant: you are no longer servant or slave but son, and if a son then an heir of God through Christ (Galatians 4:7). Many born again believers do not know why they serve their Father God? And have so many questions about the attitude they should be having when they are serving the Lord. We will not be having an exhaustive study but will try to make it as succinct as possible, going straight to the point, many other aspect of service are developed in depth if one take each aspect of service in its own. But our purpose is to have a glance of what it means to serve the Lord.
