Am I truthful to what I teach?

Though I just started "pastoring" without license or permission, just obeying to God's call, I have discovered that this can be the most difficult job in the world. However, it's so exciting to lead someone to Christ and witnessing how God grows them in Him. In that process I have learned to trust God with them that He will make them beautiful and honorable because He loves them and treasures them despite of their weaknesses, shortcomings, and their old life. And one of them confessed that she has fallen in love with my brother. She is still in process of growing and transforming, apparently not that good and godly... (you would all understand what I mean). She can be changed for the betterness by God I said to her many times, but now... for my brother? Do I still believe the same? Good question to ask. Not easy to answer. Am I truthful with what I teach her? It's not a question of doubt but of integrity and what...I can't explain clearly. But this is what I am learning. "God, you really want to train me to be a leader of integrity, faith, and truthfulness?" How interested is our God!
