who is the happiest mankind in the world?

Spirit Filled Christians!

Happiest mankind in the world is a person lives without religion or any group. Because without religion we feel the test of freedom.

Someone who has loved and been loved by someone is the happiest mankind in the world

Those who have been filled with the Holy Spirit and have felt the hand of God touch their heart, they know that eternity awaits them and there will be no end of celebrating then

I used to find hapiness in a can of beer, but the depression I got far outweighed any short term happiness. There is no high like the Most High God.

I'll just assume you were asking - who are the happiest people in the world: Africans. Truly. There is a certain beauty in their spirit and their connection with one another - the more tribal their life, the happier they seem. Maybe they are the choosen people.

The one who has all the fruits of the Spirit! :) and the peace and joy of God which surpasses all understanding! Amen!

Galatians 5:22

But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness,

Philippians 4:7

and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus.

Psalm 35:9

And my soul shall be joyful in the LORD;It shall rejoice in His salvation.

Matthew 25:21

His lord said to him, ‘Well done, good and faithful servant; you were faithful over a few things, I will make you ruler over many things. Enter into the joy of your lord.’

Me, i am the happiest man in 2 meter from where i sit.

the forest or cave dwellers, ancient civilzations without the effects of commerlization, industrialization, money madness, being clothed, their wants are limited, what pleases and delights them are limited, they do not want to go beyond that, thus they are the happiest - because they are happy - with what they have!!!!

Every single person in this planet is mankind. So I'd have to say earthlings.

depends on haw you define "mankind". generally "mankind" refers to all humans, so it doesn't make sense to separate "the happiest mankind"
