"A relationship between a man and a woman in which they seek to determine if it is God’s will for them to marry each other" puts marriage on the table when the couple have not yet committed to such an end.
This is no different than dating when two people get too intimate too fast (I do not mean sexually) and give away a piece of their heart. I am now married to a wonderful Christian man and we have 4 children.
A dating relationship is usually based only on what the dating couple presently knows about each other.
In contrast, a Biblical courtship is based on what God knows about each partner and on His plans for their futures.
(See Proverbs 3:5–7.) Courtship is a choice to avoid temptation and experience the blessings of purity.
It is a choice to not emotionally give away your heart, piece by piece, to many others through casual dating relationships and instead to give your whole heart to your life partner.
A couple participating in courtship seeks the accountability of their parents or other mentors.
If defrauding (stirring up desires that cannot be righteously satisfied) occurs, the couple can foolishly and tragically give away both emotional and physical affections that should have been reserved for a life partner.
Thus, in a dating relationship, frequently intimacy precedes commitment.
A courting couple can evade numerous temptations by the choice to be held accountable to God-given authorities.
The dangers of defrauding can be avoided more successfully, and an honest, open friendship can be nurtured and protected. Since one of the most important decisions we will make is the decision of marriage, we should make every effort to know and do God’s will in this area.
In a dating relationship, self-gratification is normally the basis of the relationship.
