One of the simplest and easiest way to serve GOD and others is by be friendlies one another. 

I give my full heart to serve our GOD together with my brother and sister in church and really loves to serve to LORD. :)))

Joshua 24:15
"if it is disagreeable in your sight to serve the LORD, choose for yourselves today whom you will serve: whether the gods which your fathers served which were beyond the River, or the GOD of the Amorites in whose land you are living; but as for me and my house we will serve the LORD."
