When you are joined to someone in marriage, you are yoked together. You carry and share each other joys, strengths, and weaknesses.
What your spouse does and how they live, their lives should, therefore, be of great concern to you. You cannot afford to be unconcerned or nonchalant about the life your spouse lives because it will affect you whether good or bad.
The irony though is that though you are now one with your spouse, they still do have a mind of their own. This is where prayers come in. You want to pray that God directs and lead them in ways that will bring blessings to your home. I was going to list some prayer points to pray for your spouse and then I found this blog that has already done all the work nicely https://www.ibelieve.com/relationships/30-day-prayer-challenge-for-your-husband.html
Even though it was written for the wife to pray for her husband, I honestly think it can be adapted for the reverse as well. God bless you. Prayer is still the Key!
