The concept of commitment flows directly out of the worthy walk. Verses 2 and 3 imply a long term, on-going relationship with other believers. They paint a picture of people involved with one another at a level deeper than shaking hands after a Sunday service. Our culture is generally opposed to the concept of commitment. We see commitment evaporating all around us.
Marriage is no longer a life time partnership.
People build relationships selfishly, looking for whatever they can get out of them. There is little concern for the other person. When the going gets tough, the relationship is abandoned. It is much the same with employers and employees. This lack of commitment has spilled over into the church.
