What is the difference between the teachings of Jesus and Krishna?

Answer:

Essentially there is no difference in the message of Krishna and the message of Jesus. Like father, like son. The very essence of Jesus' teachings is bhakti, or pure devotion to the Supreme Being.
Jesus was preaching perfectly, and his universal message is nondifferent from the teachings of Krishna.

Examples are as follows:

Message of Jesus :-

Man has to change his heart, give up sense gratification and turn to God with complete determination--"Thou shalt love The Lord Thy God with all Thy heart, with all Thy soul, and with all Thy might."

Bhagavad-gita
"Always think of Me, become My devotee, worship Me and offer your homage unto Me. Thus you will come to Me without fail. I promise you this because you are My very dear friend" (Bhagavad-gita 18.65).

"To those who are constantly devoted to serving Me with love, I give the understanding by which they can come to Me" (Bhagavad-gita 10.10).

"To show them special mercy, I, dwelling in their hearts, destroy with the shining lamp of knowledge the darkness born of ignorance" (Bhagavad-gita 10.11).

The great Spiritual master Srila Bhaktivinoda Thakur teaches:
manasa deho geho jo kichu mor arpilun tuwa pade nanda-kisor
"My mind, my body, my home, whatever I have in my possession, I offer unto You, my Lord."

Srila Rupa Gosvami, the direct disciple of Sri Krishna Caitanya, says:
sarvopadhi-vinirmuktam tat-paratvena nirmalamhrsikena hrsikesa-sevanam bhaktir ucyate
"When all one's senses are engaged in the service of the Supreme Lord, the master of all the senses, and the soul renders pure service unto the Supreme, he is freed from all material designations, and one's senses are purified" (Narada-pancaratra qtd. in Bhakti-rasamrta-sindhu 1.1.12).

The message is the same: Jesus was preaching intense spiritual life; to forsake, home, relatives and the rest and turn to God radically in pure devotion.

"…and if you wish to be perfect, go, sell your possessions, and give the money to the poor, and you will have a treasure in heaven. Then come, follow me" (Matthew 19:21).

"…Do not worry about anything: look at the birds of the air; they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than them?"

"…And why do you worry about clothing? Consider the lilies of the field, how they grow; they neither toil nor spin, yet I tell you, even Solomon in all his glory was not clothed like one of these. Therefore do not worry, saying, 'What will we eat?' or 'What will we drink?' or 'What will we wear?' But strive first for the kingdom of God and his righteousness, and all these things will be given to you as well (Matthew 6:26-33).

"Ask, and it will be given you; search, and you will find; knock, and the door will be opened for you. For everyone who asks receives, and everyone who searches finds, and for everyone who knocks, the door will be opened. Is there anyone among you who, if your child asks for bread, will give a stone? Or if the child asks for a fish, will give a snake? If you then, who are evil, know how to give good gifts to your children, how much more will your Father in heaven give good things to those who ask him." (Matthew 7:7-11).

One disciple said to him: "Lord, first let me go and bury my father." Jesus said: "Follow me. Let the dead bury their own dead" (Matthew 8:20-22).

All it depends upon is the surrender of the soul and complete abandonment to the will of the Supreme Lord: "Father, if this cannot pass unless I drink it, your will be done…" (Matthew 26:42); "Your kingdom come. Your will be done, on earth as it is in heaven." (Matthew 6:10).

Here we hear the same old voice that is speaking at the heart and root of any genuine tradition: As the result of such surrender, Sri Krishna reveals Himself to His devotee:

ye yatha mam prapadyante tams tathaiva bhajamy aham
"As they surrender unto Me, I reveal myself" (Bhagavad-gita 4.11). Never mind religion, race or nation: samo 'ham sarva-bhutesu na me dvesyo 'sti na priyah - "I am not partial to anyone. I am equal to all" (Bhagavad-gita 9.29).

sarva-dharman parityajya mam ekam saranam vraja

aham tvam sarva-papebhyo moksayisyami ma sucah

"Abandon all varieties of mundane religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear." (Bhagavad-gita 18:66).
