Close to his heart were the matters of salvation, his social engagement (charitable work), and "fight against alcohol.

His father, Alexander Barratt, led the sulfur mining operation at Varaldsøy in Hardanger and moved there alone in 1867.

As an eleven-year-old, Barratt was sent to a Methodist school in England and received salvation at twelve years of age.

He received his theological education at Wesleyan Collegiate Institute in Taunton, now known as Queen's College, where he also studied art and music.

He founded Byposten ('The City Mail'), now Korsets Seier ('Victory of the Cross'), which was first published on 27 February 1904.

In 1902 Barratt founded Kristiania Bymisjon ('Kristiania city mission'), a social work organization.

During his stay in New York, he sent reports about Christian life in America to Norway, which were published in the newsletter Byposten.

Barratt had long desired baptism in the Holy Spirit, and in September 1906 he came across the newsletter The Apostolic Faith, published by the Azusa Street Mission.

It challenged him to give his life and plans to God, so he prayed and experienced a breakthrough on 7 October 1906, being baptised in the Holy Spirit.

I was, like Daniel, completely helpless during God's divine touch and had to support myself with a table on the platform where I sat and slid down onto the floor.

I asked a brother (a Norwegian) who had often heard me preach in Christiania, and the doctor's wife, to pray for me yet again.

Los Angeles has been visited by an awakening reminiscent of the one described in the second chapter of Acts"[10] and "A flash of light from the west.

After the children went home, the room was filled with adults for a Pentecostal revival that lasted all night.

In 1909 the leading actor Anna Larssen Bjørner gave up her high-profile career to become an evangelist.

[12] The Methodist Church desired to distance itself from his charismatic direction and terminated his membership in 1909, after which he travelled to the UK once more, preaching in Sion College, London and then returning to Sunderland for what had become an annual Pentecost celebration known as the Whitsuntide Convention.

He then visited Bournemouth and stayed with Stanley Frodsham, another early Pentecostal pioneer and writer.

The Free Evangelical Fellowship, led by pastor Erik Andersen Nordquelle, had their meetings in Oslo and allowed Barratt to use his pulpit; the two developed a close cooperation.

Nordquelle led the Free Evangelical Fellowship and Barratt's meetings were to become the Norwegian Pentecostal movement.

[13] Despite the opposition, or as a result of media attention and gossip, the revival in Oslo quickly spread throughout Norway—several existing Norwegian parishes also joined the movement.

His preaching marked the beginning of the meetings at All Saints' Church in Monkwearmouth, Sunderland, under the ministry of Boddy.

On 13 September, Barratt wrote "the eyes of the religious millions of Great Britain are now fixed on Sunderland."

[14] Barratt continued to travel abroad, visiting Sweden, Finland, Poland, Estonia, Iceland and Denmark.

Nevertheless, they faced disagreements as the Smith brothers could not accept Barratt's preaching that sin was removed through baptism in the Spirit.

Both he and his wife Laura were baptised on 15 September 1913 by Swedish pastor Lewi Pethrus at the Filadelfia Church in Stockholm, Sweden.

[8] Barratt was said to have had a slightly bowed and rocking gait, a mild, pleasant disposition, and a good sense of humor.

Musician Karsten Ekorness [no] was active in Filadelfia Oslo the last twelve years of Barratt's life.

Barratt's last solo in church (at Filadelfia Oslo) was the first Sunday of 1940 and Ekorness accompanied him on piano.

Early on, Barratt established the Pentecostal Foreign Mission of Norway (De norske pinsemenigheters ytremisjon, PYM) which sent missionaries particularly to countries in Asia and Africa.

Its name was changed in 1910 to Korsets Seier, and it remains the primary mouthpiece for the Pentecostal movement in Norway.

Barratt wrote a number of devotionals and articles in Christian publications, especially for Byposten, or Korsets Seier, as it is known today.
