Question: "What should I be looking for in a husband?"
When a Christian woman is looking for a husband, she should seek a man after Gods own heart (Acts 13:22). The most important relationship that any of us have is our personal relationship with the Lord Jesus Christ. That relationship comes before all others. If our vertical relationship with the Lord is as it should be, then our horizontal relationships will reflect that reality. Therefore, a potential husband should be a man who has his focus upon walking in obedience to God's Word and who seeks to live so that his life brings glory to God (1 Corinthians 10:31).
What are some other qualities to look for? The apostle Paul gives us the qualities we should look for in a husband in 1 Timothy chapter 3. In this passage are the qualifications for a leader in the church body. However, these qualities should grace the lives of any man who walks after God's heart. The qualities can be paraphrased as follows: a man should be patient and controlled in his demeanor, not filled with pride but of sober mental attitude, able to master his emotions, given to graciousness to others, able to patiently teach, not given to drunkenness or uncontrolled use of any of God's gifts, not prone to violence, not overly focused upon the details of life but focused upon God, not apt to be a hot-head or be thin-skinned so that he takes offense easily, and grateful for what God has given, rather than envious of what gifts others have received.
The above qualities describe a man who is actively engaged in the process of becoming a mature believer. That is the type of man a woman should look for as a potential husband. Yes, physical attraction, similar interests, complementary strengths and weaknesses, and the desire for children are things to consider. These things, though, must be secondary to the spiritual qualities a woman should look for in a man. A man you can trust, respect, and follow in the path of godliness is of far greater value than a man of good looks, fame, power, or money.
Finally, when looking for a husband, we must be surrendered to God's will in our lives. Every woman wants to find her prince charming, but the reality is that she will probably marry a man with as many flaws as she has. Then, by God's grace, they will spend the rest of their lives together learning how to be a partner to, and servant of, each other. We must enter into the second most-important relationship of our lives (marriage), not under an emotional cloud, but with eyes wide open. Our most important relationship, with our Lord and Savior, has to be the focus of our lives.
