Most of life is made up of the unknown. Not everything is crystal clear and direct from God. Most of the time I have to be willing to trust and not doubt that He is leading because I can't always see the way through from start to finish. This goes contrary to our natures. We want the answers and we want the solutions and we want them now.
Conscience is the still small voice that keeps leading and guiding.
The problem often is, however, that their are conflicting voices. That means I am going to have to concentrate and listen carefully to hear it because that voice is the stabilizing factor for my faith when I don't know for sure which way to go. I have to train myself to listen for the quiet voice when I am be bombarded with the loud overwhelming sounds of the world and the devil. A tough verse is number 20. Those who made shipwreck of their faith by not having a clear conscience were handed over to Satan so they could be taught not to blaspheme.
