Dr. Gary Smalley reveals the true foundation of every great marriage.

In I Promise, America's foremost marriage expert comes to a startling new conclusion: great marriages are built on a foundation of trust, not behavioral skills. So it's not enough to learn your partner's love language, become proficient in conflict resolution, learn to control your emotions, or even become an expert in the bedroom.

If your spouse does not feel safe enough to open up his or her heart without fear of being judged, criticized, blamed, or rejected, nothing you do will be effective. It's only when couples feel emotionally safe that they can truly become one as God intended. Based on ten years of research, Dr. Gary Smalley shares five heartfelt promises you can make to your mate that are guaranteed to build trust and help your spouse become the true soul mate, lover, and friend you desire.
