How can I be a caller to Islam?

For a caller to Allah to be successful in his call, he must possess essential qualities, including: deep faith in what he calls to, and a close connection with Allah through sincerity, love, and worship of Him. He must also have knowledge and insight into what he calls to, act upon what he knows, and maintain righteous conduct. The caller must be aware of the reality of the call and the people being called, be wise in his approach, possess good character, think well of Muslims, and conceal their faults. He should also mix with people when mixing is beneficial and withdraw from them when withdrawal is beneficial, treat people according to their status, and cooperate and consult with other callers.
