Christians face complex questions about sharing faith, medical ethics, suffering, and relationships that don't have simple answers. When approaching non-believing friends, it's important to lower expectations and lead with love rather than judgment. Regarding fertility treatments like IVF, the key concern centers on when life begins and what happens to unused embryos. Suffering serves as a reminder that this world isn't our final home and drives us back to God. For parents concerned about adult children's faith, authentic living often speaks louder than arguments. While we may not understand why difficult things happen, we can trust in who God is - the One who loved us while we were sinners and remains faithful even in our confusion.
