Biblical Answer

Happiness can be restored after losing a partner, but it requires commitment to the relationship and a willingness to work through challenges. According to the Bible, a spouse is a covenant partner, and there is a need to rekindle the heart and renew the commitment in the relationship (Proverbs 2:17). This means putting the happiness of the spouse ahead of one's own, in a sustained way, in response to what Jesus has done for us (Ephesians 5:21). When we prioritize the happiness of our partner, we will find a new and deeper happiness ourselves (Matthew 7:12).

The process of restoring happiness in a relationship can be challenging, especially when dealing with issues like depression. However, it is possible to overcome these challenges and find happiness again. The key is to persevere and continue to communicate with each other, even when it feels like it's all downhill. As the Bible says, "Love is patient, love is kind. It does not envy, it does not boast, it is not proud" (1 Corinthians 13:4). When we choose to love and serve each other, we can find a new and deeper happiness that is not based on natural affection, but on the love and commitment we have for each other.

Ultimately, restoring happiness in a relationship requires a commitment to Jesus and His teachings. When we look to Him, we will find strength and guidance to navigate the challenges of our relationship. We will also discover that our greatest joys often come from striving, desiring, and being deeply attached to each other. As the Bible says, "Love never fails" (1 Corinthians 13:8). By choosing to love and serve each other, we can find happiness again and build a stronger, more meaningful relationship. This requires a willingness to work through challenges and communicate with each other, but it is possible with Jesus' help and guidance.
