In 1959, a separate gymnasium with classrooms and a kitchen was built on an adjacent lot. Men of the congregation built this building, as they did the sanctuary and parsonage. The Women's group supplied the kitchen using donated S&H Green Stamps. It was a time of sacrificial giving and labor by Pastor and people alike, driven by their desire to honor the Lord with a place of worship and outreach. An old, dilapidated house on the property was fixed up and became a parsonage for a succession of associate pastors and their families. It continues today as a rental property.

In August 1962, Rev. Richard Tevebaugh came to minister to the church. A highlight of his ministry was the beginning of an annual missions conference and the Faith Promise program of missionary support. In 1964-65, Bill and Marion Baldwin (GEM-Greece) became the first missionary interns and received church support throughout their 68+ years of service. As the missions budget increased so did the number of missionaries supported by the church.

Rev. Howard Westlund was called as pastor in September 1969 and served until 1995. During his time attendance grew and fellowship groups, Bible studies, youth groups, and missionary support were all expanded. In 1974 missions giving totaled $46,235. In 1975 Sunday School neared 400 in average attendance.

Primarily with the foresight and hands-on efforts of Howard Westlund, the congregation voted to begin a remodeling and addition program to the church building. When finished, it would connect the original building to the education building, add offices, restrooms, a large reception room and an ample foyer on the upper level, plus classrooms, restrooms and a small gym on the lower level. Men of the church worked on Tuesdays, Thursdays, and Saturdays under the leadership of David Weissing. The addition was dedicated in 1979.

The 80’s were a high point of the church. Pastor Westlund was known for his counseling ability. He and David Dillon, associate pastor, were able to assist many with practical and biblical advice. Dillon also conducted special seminars and biblical teaching times. Largely because of this practical outreach, along with a strong pattern of visiting in homes and the energetic youth program under Rich Tuttle, attendance grew exponentially. Tuttle regularly visited the high school in order to meet and invite students and formed leadership/discipleship groups among those who attended.

Pastor Howard Westlund completed 26 years of ministry in 1995 and left soon after to serve as an interim pastor in the United Arab Emirates.

Tom Terry, returned missionary from Greece, served as interim pastor for one year, becoming senior pastor in 1996 through 2000. As the year 2000 came to a close, Pastor Tom Terry resigned to return to service with the Greater Europe Mission.

In April 2001, Dr. David Fetzer, Professor of Communications at Moody Bible Institute, came as interim pastor. The Spanish church continued as a Sunday School class only. All church debt was paid off by year-end and missions giving totaled a high of $119,320.

In November 2002, Rev. Paul Rhoads became Senior Pastor and the focus on reaching the community for Christ continued. In November 2005, Paul Rhoads resigned. Rev. Clark Wooten came as interim pastor in early 2006. His gentle wisdom and love of people effected much needed healing. In late 2006, David Fetzer again assumed the interim role as the Senior Pastor search continued.

In July 2007, West Chicago Bible Church merged with Water’s Edge Church, a small congregation meeting in a school and pastored by Tod Eenigenburg. He become pastor of the resulting merged church. The new church was named Water's Edge Bible Church. In April 2010, Pastor Tod Eenigenburg resigned unexpectedly.

In 2014, Jayson York became pastor. Marked by expository preaching, his ministry emphasizes strict adherence to the truth of the Word of God throughout church programs.

Voting at the June 24, 2018 Annual Meeting affirmed the membership's desire to change the church name back to West Chicago Bible Church.

Attendance has steadily increased, and membership has grown, as WCBC continues its outreach to the local community, the country, and throughout the world.
