That truth has brought immeasurable emotional pain and other consequences to many Christians.
Worse, it has brought great dishonor to the name of Christ and to the witness of individuals and the church. For Christians, the Lord has given us his Word, and the Holy Spirit helps us to understand it.
Some things it talks about explicitly, like salvation, or sanctification, or marriage, or elders.
The Bible guides us in some areas by broader, more general principles and ideas we can build on as we strive to live the Christian life in practical ways.
Modern dating tends to assume that a good relationship will "meet all my needs and desires," and a bad one won't — it's essentially a self-centered approach.
Biblical dating tends to be complimentarian (God has created men and women differently and has ordained each of these spiritual equals to play different and valuable roles in the church and in the family).
In either case, no area of life falls totally outside of the guidance and authority of God's Word.
My point is that we cannot simply state that the Bible "doesn't mention dating or courtship," and then think we're off the hook to pursue this area of our lives either on the world's terms or however seems best to us without diligent, submissive reference to God's Word.
Modern dating tends to assume that you will spend a great deal of time together (most of it alone).
Biblical dating tends to encourage time spent in group activities or with other people the couple knows well.
