How to love God and love another one?

I want love God, love another one, I want build a good relationship with God, but I really do not know how to do that, please help me Lord.

I think important thing is love God and others use your heart

You just took the first step! Now, trust God!
You’ve asked for His help because you can’t do it on your own. (NOTE: none of us can!)
Now you let Him refine you, and He will. Trust Him.
