Rather, speaking the truth in love, we are to grow up in every way into Him who is the head, into Christ, from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love.” (Ephesians 4:15-16)

Small Groups

Small groups make up the community core which forms the basis of our church. Because they play such an important role, we would like to encourage those of you who attend OIF to be a part of one! Meeting once a week gives us a chance to share, enjoy, and learn together in a way Sunday church doesn’t allow. Read more.

Sunday Training classes teach believers God’s Word to equip them to minister to others wherever God sends them. We invite everyone to come and attend on Sunday mornings at 10am in the OIF Hall. Listen to recordings of previous Sunday Training classes here.

At OIF, we strive to see every believer grow deeper in their walk with God no matter what stage you are at spiritually. We offer mentorship programs (1-on-1, 1-on-2, special trainings) to help you grow in your spiritual walk. Read more.

Missions Department

The Missions Department is responsible for communications with the missionaries that the church supports. We keep in touch on a monthly basis to pray for their needs and send them financial support on a quarterly basis. Every year, we have a Missions Focus Weekend to build awareness of what God is doing around the world, sustain the church’s heart for sharing the gospel cross culturally, inform the church who the supported missionaries are and encourage the church to care for them.

Welcome Team

The Welcome Team shows God’s love to guests and regular attendees by being a friendly face and helping them feel welcome each Sunday. We hope to help visitors get to know our OIF community and connect with our church members and small groups. We greet before Sunday services, have lunch with visitors during the fellowship lunch at the Guest Connections table, and follow up with our guests.

Worship Team

The Worship Team seeks to cultivate a community that celebrates the King and the diversity of His Kingdom through musical worship. We do this by

  • leading the OIF congregation into worship of God, joyfully, faithfully, and creatively through music and traditions that reflect all nations
  • recruiting and discipling people from all nations who can lead the congregation in worship
  • growing as individuals and as a team in our love and knowledge of the Lord, as we join in the Holy Spirit’s work of drawing all nations to Jesus.

Facilities Team

The Facilities Team serves to keep the practical function of the church building and equipment in good working order. We oversee both a spring cleaning in preparation for the summer and then a fall reset of heaters and more for the winter months. At times we will install new equipment, and we continually seek to improve the service of the many ministries and groups that use the PCCO and OIF facilities.
