Brother, remember that you are beholden to the Lord's timing and preferences, not your own. You might not feel that now is the time, but then again, you will likely be saying the same thing years down the road -- life will continue to be just as busy! If you like this women, consider her to be godly, and have the means of staying in touch and building a relationship with her, let me urge you to at least reconsider. Imagine the many benefits of having her work alongside you and support you in your ministry and work life. A godly spouse will ease your load and make life easier, not be an additional burden.
