Even for millions of births if we don't actually come to that stage of chanting without offenses then we can never get love for Krsna. But if one goes on chanting with the understanding, that "Yes, I still have some attachments from within my heart, I have some anarthas within my heart, but I'm always very, very careful to avoid these offenses to the Holy Name of the Lord. If one continues to chant in this mood then gradually he will become free from offenses.
