The gospel changes everything. When we repent of our sin and trust in Jesus' death and resurrection for our salvation, we enter a whole new world. God changes our desires, our behavior and our thinking. But what does this inner change mean for our external circumstances and our relationships with friends, family and coworkers? And in particular, what does it mean for marriage? Does our new relationship with Jesus invalidate marriage? What if you're married to someone who rejects the gospel? Should you stay bound to a non-Christian?
