Today we read about entering the kingdom by the narrow door, the road to perdition being wide. What is Jesus saying?
As we grow in the Christian life what we are about as Christians comes more and more into focus. New damands are made upon us, we are constantly asked to choose Jesus in all situations and we find ourselves less and less at ease with things outside the sphere of Christian living, eg. we may feel called to stop reacting in certain circumstances about issues at work, we may feel called to more prayer, we may be called more and more to make allowances for others. All of these things are the narrowing of the road, in that Jesus is asking us to forego our will and look only to him.
Also, in our life Jesus and his desires for us become ever more important. We no longer feel the call to idle about TV or gossip. Such is the narrowing of the path!
