Mary
I don't know if she is the best example given in the Bible, but I have always been impressed by the humility of Mary, the mother of Jesus.
The angel Gabriel comes to Mary and says to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; and for that reason the holy offspring shall be called the Son of God." To this unbelievably and life-altering news, Mary replies, "Behold, the bondslave of the Lord; be it done to me according to your word."
I have always wondered whether she said this with trembling lips, or if she had full confidence and peace at that moment. I am inclined to believe the first - but nevertheless, it represents great faith and humility on her part. She was a young girl, engaged to be married. What a self-centered time that can be for a girl! In the midst of perhaps the happiest time of planning in her life, she is told that her life will never be the same. Granted, it was an esteeming position to be placed in by God. But probably not very esteeming in the eyes of those she lived near, and to her friends. It had the potential to ruin her relationship with Joseph, apart from the fact that God intervened. She could even have been stoned for the sin of fornication. Yet she accepts this message from the Lord with a resigned spirit, ready to fulfill God's will for her life.
I wish I approached the small "bumps" in the road that God places in my life with such faith and humility as Mary!
