All mankind was divided into three classes: the intenders, the endeavourers, and d performers. In life u will find that there are those who intend to be involved in a relationship but can never commit to it for reasons best known to them, those who endeavour to enter into a relationship but loose steam at some point and the performers who are committed to it by faith believing that no matter what it takes all will be well.
I sometimes get the impression that commitment is a vanishing commodity in today's world. Many people don't want to be committed to their jobs, their mariage vows, or to one another in a relationship. What is commitment? Commitment is defined as a pledge, a promise or to give in trust or charge.
The replacement of faith by fear of the unknown is the cause of lack of commitment in most relationships. Marriage will not last when commitment is only one-sided. This is because a marriage is a relationship that requires full commitment and dedication, by both persons involved.
Even though for building a family it takes the commitment of both partners in a marriage relationship to raise 'Godly children' so if either spouse shows a lack of commitment in any way the influence negative impacts on the lives of the children.
