To be honest earthly happiness is now why we have life. Maybe before the apple it was. But since the apple things changed. Our real happiness is after we die. The point of being alive is to worship God and in this case spread the Word. Crossing the finish line despite the suffering is our goal in terms of making it to the end. People who focus on happiness in this life have missed what the bible talks about. It isn't to say what we do isn't important in this life, because after all we are to spread the Word so others are saved.
Which is why I find many divorcees refuse to accept they had to stay married to whoever they were with, even in abusive situations. You are 100% going to have problems in life, even problems that are so hard you probably wish you were not alive. So trying to outrun every problem is not possible. Does this mean someone has to stay with someone who for example beats them daily? No. What it does mean is you still have to remain married and MOVE out or kick them out. As a christian you cannot divorce them. They will either try to work things out with you or they will divorce you. In which case fight the divorce. If all else fails and you are stuck having to sign papers then do so of your own free will.
But divorcing means staying single forever after said divorce because in Gods eyes you are still married. Now people are often like "Wait what?!? So your saying I have to remain single just because they chose to divorce me? That doesn't sound fair! What about my life and happiness?".
Well what about it? Sacrifice, suffering...etc are part of our life while we are in these bodies. Me? I am disabled, I have bad health and often it gets worse. I've lost so much of my life from my health issues that I used to hate God for it. I felt He didn't care because my He wasn't giving me what I want and I wasn't happy. Then I realize I was so focused on being happy in this life that I failed to see being happy is not the point of this life. I mean theres nothing wrong with lets say going to see a movie or going camping...etc. But its not our mission here. Its not our end goal.
And I said this with caution if God forbid it happens to me, but this is why going into a marriage means realizing the sacrifice required not only to be married, but if the marriage ends too. When I think of what I would do if my wife even left me, I think it would be very hard. I'd probably get frustrated to at first because being single forever seems unfair. But I'd then accept it. I have to. I have no choice in the matter. Unless I care to marry someone else and have God scold me when I stand before Him because I was living in sin and committing adultery with someone since He still sees me as married to my wife. Which is why the best thing one who is divorced can do is pray they can remarry their spouse one day if things get better.
Or if the ex passes away you can marry someone else. My wifes mother never divorced her husband because it was against the law in their country. About two years ago, after waiting 29 years, the husband died and she was free to look for love again. Now shes looking! It was a hard sacrifice for her to wait that long since her husband had moved on and had another family with some other woman, but she survived the wait and feels wonderful.
And honestly I find to many adults today just marry young because of peer pressure and feeling they have to marry young because everyone else is and they have to have kids right away...etc. They watch so many worldly fantasy "happily ever after" movies and don't understand thats not real life. Its a fairy tale. Which is why I tell them do not look for love or marry until your over 25, maybe even 30. Studies have proven are brains are not mature enough to handle marriage before 25. We still have that teen thinking stuck in us that makes us take action first, then think later. Where as when our brains mature, we think first, then take the right actions....usually.
