Servant vs Son
A servant does what he has to do out of obligation or because he gets paid. But a Son does what he does because he gets to and requires no pay! God says we are no longer servants but sons! So that thou art no longer a bondservant, but a son; and if a son, then an heir through God. ~ Galatians 4:7 A servant is accepted and appreciated based on his contribution. A son is accepted and appreciated based on his position, not his contribution.
