About Oneness

What if the key to a strong marriage isn’t loving harder—but becoming one through Christ?

Oneness: Rekindle Your Marriage by God’s Design is an honest look at what happens when two imperfect people invite a perfect God into their marriage.

Eric and Erin Coss share real stories and biblical insights that reveal how unity is the heartbeat of a lasting relationship.

Each chapter blends:

+ God’s Voice — truth from Scripture.
+ His Voice — a husband’s insight and real-life lessons.
+ Her Voice — a wife’s practical encouragement.

Whether your marriage feels strong or stretched thin, this book will help you rebuild connection, rekindle joy, and rediscover the beauty of becoming one—God’s way.

When God stands at the center of a marriage, the two don’t just stay together—they become one.

About the Group Study

Marriage grows best in more than one place.

After spending meaningful one-on-one time exploring Oneness together as a couple, take the next step into the small group Bible study experience. This study invites you beyond private reflection and into a community of couples pursuing the same goal—strong, Christ-centered marriages.

Through real-life stories, shared discussion, and biblical truth, couples gain wisdom, perspective, and encouragement from others who understand the real challenges and joys of marriage. No pretending. No perfection. Just honest growth.

When couples gather in a small group setting, personal insights deepen and faith is strengthened. Scripture-based discussion and prayer create an atmosphere of discipleship, accountability, and hope—where marriages are supported, refined, and renewed together.

Because marriage was never meant to be lived—or strengthened—alone.
