Relationship Fitness
Preparing yourself for the love you desire — by Thomas Marks
Most Christians enter relationships hoping the right person will complete them. This book flips that model. Using the Six Pillars of Relationship Fitness, Thomas Marks walks you through an honest, scripture-grounded self-assessment to help you become the partner you want to attract.
What you'll walk away with
A clear picture of where you are in all six areas of relationship fitness
Practical exercises and honest self-assessment questions for each pillar
Scripture-grounded perspective on what it means to be a ready partner
A framework for evaluating compatibility beyond surface-level attraction
The mindset shift required to stop searching for the right person and start becoming one
