The first camp meeting was in 1953 under the late Pastor Essien who was District Pastor at Cape Coast. Oda was part of Cape Coast District. In 1980, Oda was carved out of Cape Coast District. Another great event started at Asamankese in the early 1950. Late Mr. S. D. Bennett-Lartey started a small Sabbath School branch after his retirement from Korle-bu Government Hospital at the Pharmacy unit. They were joined in worship by Lt. Col. Isaac Buabeng from Asamang Tamfoe and Mr. F. Ankomah-Afranie.

A Literature Evangelist, Mr. M. E. D. Ansah was transferred from Abiriw Akuapem to Asamankese to assist in the evangelistic work. After the death of Mr. S. D. Bennett-Lartey, Mr. Amoah did a very good job by bringing together some faithful ones like Alice Apea Tawiah, Elizabeth Ayeh, Leticia Lartey, Noah Appiah, R. Y. Tawiah, late Mary Kyerewaah and Madam Wilson. From this humble beginning in 1933 at Ayirebi, the Oda District at Oda has produced the following districts: Ayirebi, Oda East, Oda West, Asamankese South, Asamankese North, Kade, Ofoase and Oda North.

The other part of the history of the churches/districts that were brought together to form the current Diamondfield Ghana Conference began with the Ntoaso church in the then Abiriw district. It began when the late Master Ankra relocated his private school from Duadekyea to Ntoaso in 1952. A conversation that ensued between him, one Dr. Nartey and Madam Rebecca Aba Odum who had come to seek medical care for her sick daughter was the beginning of the seed that sprouted to form a church at Ntoaso. Master Ankra and the brethren met to study the word of God and Adventist beliefs together with the late Chief of Ntoaso at the La quarters of the village.

Madam Odum narrated what transpired at the Clinic to her husband and together they joined the small Adventist group. Master Ankra taught his pupils Christian songs and Bible verses for recitals. This inspired many people to get close and join the young Adventist family. As they prepared and got ready for baptism, including the late Shadrach Adama Dowuona, the husband of Madam Odum, the baptism was cancelled by Pastor Agboka because all those that were ready for baptism were in polygamous marriages. Afterwards, they all stopped coming to meetings of the church.

The late Pastor B. C. B. Debra, after carefully teaching the remnant, prepared them for baptism in 1956. The baptism was performed by Pastor Welch in the Densu River. The Lord added people daily to the flock until in 1961, the first camp meeting was held at Ntoaso. At the camp meeting, a ram, Bible, Hymn Book and cash was given to the chief and his elders in appreciation of a parcel of land released to be used to build a chapel for the church.

In order to sustain the gains, a request was made to parents of Hansen Road SDA Church to allow their wards to be taken to Ntoaso on weekends to boost the morale of the youth. Prominent among the youth who came were E. O. Abbey (a retired Minister), Eddie Lartey, Emmanuel Antwi, Joseph Nii Ayi Hammond, J. J. Nartey (a retired Minister) and E. O. Sackey (a retired Ministered).

The quest for further education coupled with lack of employment forced the youth to leave the town to Accra and elsewhere in order to meet their aspirations in life. As those who could read and write left the town, the membership dwindled. The Ghana Mission of SDA Church sponsored an evangelistic campaign led by Pastors H. V. A. Kumah, E. O. Abbey, M. A. Bediako and then Evangelist A. L. Ewoo.

The establishment of a church at Nsawam gave more impetus to Adventism and the message spread to nearby towns and villages. By the abundant mercies of God, from a humble beginning the district has grown and has been re-organized into 3 – Nsawam North, Nsawam South and Nsawam West Districts.
