About Us
Family Fire is a Christian ministry committed to sharing the good news of God's design for relationships, marriage, and parenting. Together, we explore spiritual, emotional, and physical intimacy and how the Spirit empowers us to live out our faith in relationships. Romans 8:14-15 tells us:
"For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, 'Abba! Father!'''
As fellow members of God’s family, we’re here to help you fan the flames of the Holy Spirit in your most intimate relationships.
The Family Fire website offers you an extensive library of resources, written by our team of pastors, therapists, and writers. We also invite you to join our active Facebook community.
Family Fire is produced by Pastor Deb Koster in collaboration with her husband, Pastor Steven. The Kosters are passionate about using God's word to help families nurture faith formation and navigate relationship challenges. As part of their ministry, they offer live teaching events such as marriage and parenting retreats. The Kosters reside in Grand Rapids, Michigan, and are the parents of three awesome young adults.
