Sangat sanjayate kamah (Gita 2.62). 

If one associates with a thief, he develops the habits of a thief and becomes a thief himself. Similarly, if one associates with a sadhu, one becomes a sadhu oneself and is able to distinguish between good and bad. After this, one will try to learn about sad-vastu, the Supreme Lord, and in order to achieve the service of the Supreme Lord, one will surrender unto the pure devotee of the Lord.

There are two types of faith:

Laukika-sraddha: customary or worldly faith. 

Tattvika-sraddha: ontological faith. 

If one goes to the temple, pays obeisance's to the Lord or serves the devotees to satisfy the requirements of customs prevalent in the society, then this is classified as laukika-sraddha. Tattvika-sraddha, however, is completely different from this.

Sraddha means "firm faith," i.e., to not only believe in God but to have firm faith that the Supreme Lord is the lord of all other controllers or isvaras, that He is omnipotent, and that if we serve the Lord, all our familial, societal, political and other duties will be automatically served. If the Lord is satisfied, everybody is satisfied. This type of firm faith in the Lord is known as sraddhaaccording to Srila Kaviraja Gosvami.
