Marriage should be a one-way ticket. You don’t invest in one side of this journey. It is more than starting the journey, finding out along the way that you don’t like the accommodations, and deciding to turn back around. No two-way tickets should be issued.
That’s why you need to resolve that divorce will not even be an option for your marriage. Take the word out of your vocabulary.
Does the Bible make allowance for divorce? Under certain circumstances, yes. While the Bible does permit divorce in some situations, it never promotes divorce.
