1) Paul then becomes slightly charismatic and reminds Timothy that there were prophecies made over him. Not only does Paul not disregard these prophecies, but the exact opposite, as Paul encourages Timothy to maintain what was spoken, holding on to it in order that he may wage a good war. Prophecies can be used to aid in spiritual warfare. To say otherwise or to say this is in the past is just foolishness.

2) Paul closes this by reminding Timothy to have faith and a good conscience. When your conscience pricks at you, the Holy Spirit often chastises us to do a better job.  Let me give you a personal example that you won't like too much, but it happened to me and is real to me. It all has to do with bumper stickers.
