Our children see how we respond to disappointment, losing, winning, not getting our way and how we respond to fear. Children see you at your proudest moments of accomplishment and your lowest moments of failure and they imitate how you react.
But it's not just children who watch and learn and grow, we all do. We all imitate. Imitation is important, we need to be intentional about who we imitate. I suspect some of us without even knowing it or thinking about it too much imitate those who our society values without asking the question, Are my examples truly of God?
We can imitate ourselves into a rotten life or we can imitate into the very best life.
As long as you and I are alive, we are growing. If you want to grow well, imitate Christ. If you want the best for those around you show them Christ in you.
