No study on the subject of grace would be complete without addressing its importance in the home, especially between marriage partners. We have spent considerable time on God’s grace in offering salvation to those who are lost, spiritually dead, and unable to do anything to earn divine acceptance. We’ve called that “vertical grace.” And we have also searched Scripture for insight in the realm of “horizontal grace,” our attitude toward and treatment of one another. But we have not specifically considered the essential value of grace in the husband-wife relationship. As we shall see, grace is the oil that decreases domestic friction, the one ingredient that prompts both partners to release each other to be all God would have them be, all the while affirming each other in an atmosphere of unconditional love.
