Never forget the Source
I have been going to a Bible study group where we are doing a study of David. The first study was about the fact that David never forgot where he came from. His family was not in line for the throne and even if they were he was the youngest of eight brothers. Yet God picked him out of obscurity and anointed him to be king. David never forgot it and it kept him humble. “Who am I, O Sovereign Lord, and what is my family, that you have brought me this far?” 2 Samuel 7:18
About the same time I read this: Never get so dazzled by success that you forget the source of everything you have, or become so caught up in your blessings that you fail to acknowledge the One who blessed you.
