John 10:1-10 (For text see here)

It is a peculiar fact that the words of Jesus feel right even when they are counter-intuitive. The gospel always challenges those who listen, moving the world view to be closer in line with what Jesus speaks of. In this way, we recognise his voice and follow Him almost involuntarily. So what is it that happens when we hear teaching and recognise the challenge of it as truth? This internal reconciliation is not to reason because Jesus' teaching is not recorded as rational discourse; He teaches more through 'thought pictures' and stories creating feelings that are experienced. It is then the experience of the teaching that challenges the feelings of our daily lives and the process of reconciliation is therefore at a subliminal, emotional level.

This mode of 'hearing' that allows us to shape what we do such that the result of our actions measured emotionally (in our hearts). This way we act and feel in a way that does not refer to a rule or a law because we are operating at a deeper level.

In this particular example, the thought picture is of a gate - a way in and out of to a place of safety. The gatekeeper calls those who hear to safety - there is an easiness and sense of security - the one with the authority is the one who  provides shelter. It all feels as it should be - secure and sound and proper. The thieves and bandits on the other hand are the threat. They bring fear and uncertainty. They avoid the proper authority of the gate and threaten the place of safety. The feeling towards the thieves and bandits is therefore uncomfortable - a loss of the peace and security offered by the gate and the gatekeeper.

As a parable, it needs no further explanation. The feeling of spiritual safety and security offered by Jesus is enough to want to listen and hold on to Him. What threatens this is to be avoided. Simple as that.
