I would like to perhaps answer this question in the following manner,Bezrat Hashem......................: Eliezer was Abraham's must trusted servant, and fulfilled all of his duties with the utmost of care.Nothing was lacking in how Eliezer went about doing his task down to the very detail,as elaborated in the Torah.......

The Torah is in essence teaching us by Eliezers example what true service is......We need to have a paradigm of what true service is,so that we can relate that to our own service to G-d Almighty....... Learning by example is very powerful indeed.......Eliezer went about his task to serve Abraham with so much deliberation ,care and thought....that the Torah itself testifies to it in great detail.............We must therefore also serve G-d in the same manner..........The Mitzvahs of the Torah must also be performed with great detail,not haphazardly and careless......The care and love that we put into the Mitzvahs is what truly reveals our inner attitudes towards the Torah........Eliezer truly revealed his love for his master, Abraham.........This is what took Eliezer from just being Abraham's servant to making him an example to his masters future descendants ............
