- 3 Intrigue Rekindle the fascination that first drew you together
- 4 No Say "no" to the good so you can say "yes" to the best

- 6 Examine Grace-filled communication that draws you closer
- 7 Safeguard Protect your marriage — intimacy, boundaries, and your people
- 8 Teachable Spirit Keep growing — and keep investing
“We fell in love with the curriculum… I would say we were coasting before and after we are thriving. It taught us so much about keeping God at the center and loving each other well.”
“The INVEST curriculum has such practical applications that refreshed so much in our marriage that we were falling short in. We still apply so much of this curriculum in our weekly rhythms to reveal our best yes, and remind us what’s most important in our marriage!”
