He is already showing that he is unwilling to “forsake all others,” and that he is not living a pure lifestyle.
If there is always that possibility, then you must ask yourself whether this person has the qualities you will need in a husband. Ask yourself these questions: How strong is his relationship with Jesus Christ? How passionate is he about reading God’s Word, prayer, and fellowship with other believers in a biblically solid church? However, in Ephesians Paul compares a husband’s role toward his wife with that of Christ’s role toward His Bride, the Church, “Husbands, love your wives, as Christ loved the church and gave himself up for her, that he might sanctify her, having cleansed her by the washing of water with the word, so that he might present the church to himself in splendor, without spot or wrinkle or any such thing, the she might be holy and without blemish,” (Ephesians -27, emphasis mine).
Christ’s role and a husband’s role do differ because only Christ alone can truly cleanse us.
It can be difficult to be clear-headed in a dating relationship.
It is easy to see only the positive in the other person and completely ignore any warning signs. It would be foolish to date someone and not even consider the possible outcomes.
And if he is not ready to be a husband, dating him could only have a sorrowful outcome.
