God is even more than the creation. The first and foremost commandment is to love God and serve Him when He comes down in human form. For this to happen one should love others as themselves so that when God in human form approach us we can serve Him without any repulsion and we can recognize Him without any repulsion and love Him and participate in His mission of divine knowledge propagation.

We can please God by doing some social work, loving animals etc.

I think if I do any social job with full of my heart & soul ,may that makes GOD please. this is important that how much I committed with job& how much I love to do it? Without any love any social work is not happen perfectly. Then GOD gets hurt.
