Ambassador Baptist Church began in the home of Pastor Lyle and Helen Neufeld in Morden, where they initially ministered to their family and friends.

The church grew and, by March 5, 2000, began renting space at the Recreational Center before moving to the old Lutheran church building later that year.

In 2003, Pastor Lyle was ordained for full-time ministry. After 11 years, the church purchased the old Catholic Church building at 685 Stephen Street, where they have been since 2012.

The mortgage was paid off in 2015. In 2019, Terry and Jane Carruthers were called to lead the church, though their installation was delayed until July 2020 due to the Covid pandemic.
