The couple behind the Sound of Hope movement, Possum Trott, Donna, and Reverend Martin, initially started fostering children out of obedience to a vision Donna had after her mother's death. They felt compelled to take action without seeking any outcome, simply obeying what they believed was God's will. Their involvement grew into a global realization of the widespread issue of at-risk children, a situation they never anticipated. Through their obedience and trust in God, doors opened, and they found themselves in a position they never imagined. Their key takeaway is to focus on doing God's will, trusting and believing in Him to handle the rest.
