Krishna is the one who is all powerful and who can demonstrate His power.
na kartṛtvaṁ na karmāṇi lokasya sṛjati prabhuḥ
na karma-phala-saṁyogaṁ svabhāvas tu pravartate (BG 5.14)
The embodied spirit, master of the city of his body, does not create activities, nor does he induce people to act, nor does he create the fruits of action. All this is enacted by the modes of material nature.
gatir bharta prabhuh saksi nivasah saranam suhrt
prabhavah pralayah sthanam nidhanam bijam avyayam (BG 9.18)
I am the goal, the sustainer, the master, the witness, the abode, the refuge and the most dear friend. I am the creation and the annihilation, the basis of everything, the resting place and the eternal seed.
Krishna the master, the witness is the all powerful one, He can create a mammoth being like an elephant and even destroy the same. Every living and non-living entity comes from Him and ultimately can be destroyed by Him only.
Lets become intelligent and chant His powerful Holy name to make us all powerful in the path of devotion/Bhakti.
