To believe is a very deep word.
One may do a certain thing but not believe in it. One could also believe in something and yet judge it. To gain your trust on something takes time, not everything that we see or hear crawls up in our book of trust.
Whatever you may do, always believe in it, gain confidence and you may find it being loyal towards you. If you wish to create something, create it with love and it will give you love in return.
