Total absorption in hearing Sankirtana Music develops faith in Lord Krishna.
One is called a faithful man who thinks that simply by acting in Krishna consciousness he can attain the highest perfection.
Bhagavad Gita 4.39,
Hard earned money is kept in fixed deposit in the Banks and we are used to Credit Cards. Similarly deposit your faith in fixed deposit of the Lord, and chant every day.
A devotee knows that even at his death Krishna will protect him. The real test of our devotion will be at that time.
No one lives even a moment without faith, even unconsciously.
When we face difficulties and still remain faithful to Krishna and the spiritual master, we access the infinite mercy of their hearts.
