How Devotion save us from this life as well as in next life?

As stated in Srimad Bhagwad Gita chapter 2.40 by Lord Krishna to Arjuna the importance of little devotion, how can it save us from a great danger. 

नेहाभिक्रमनाशोऽस्ति प्रत्यवायो न विद्यते ।

स्वल्पमप्यस्य धर्मस्य त्रायते महतो भयात् ॥ 2.40 ॥

In this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear.

We are not even aware of how powerful this is devotion towards Lord Krishna although if we do it nicely or not but it gives us the result as much as we do. But in material activities until and unless we do not reach at the end of the task we would not get the result out of it.

That is why in devotion we can live a happy & peaceful life in present as well in next life too.

How it save us in this life?

We see there are so many faults in this age of Kali everywhere there are fights, quarrel, anxiety, tension, greed, lust and so many bad things are there and how can one live peacefully in this surroundings? But if we take shelter of Lord Krishna - the supreme personality of Godhead and render devotional service towards Him we feel relaxed and peaceful reason is He is the ultimate shelter of all living being mentioned in every scriptures i.e. Srimad Bhagwad Gita, Bhagwatam and Ramayana.

How it save us in next life?

We know the story of Gajendra the powerful elephant when he was taking bath along with his companions suddenly a crocodile come and catch the feet of Gajendra. Gajendra seems to very powerful but  he was unable to get out of the clutches from Crocodile and they fought around 1000 years.

Finally Gajendra tired and all his companion left him and he was hopeless and then all sudden he started praying to Lord Vishnu by chanting a beautiful prayers which he was learned from his past life as a king Indradumnya.

Lord Vishnu came sitting on His career Garuda and cut the neck of crocodile and saved Gajendra.
