St. Paul was a persecutor of early Christians before Jesus made him an apostle to the Gentles, and his calling came rather dramatically. For most of us, the calling is gentle and subtler. If we do not wish to turn to God, we just don't get to know him. But if we are sincere in wishing to know him, he never fails to reveal himself to us. Many converts came to know God after they pray "Lord, if you really exist, reveal yourself to me." Know that God is ever ready and eager to become one with you, so open your heart wide and he is yours!
