When the centurion had his servant healed, he demonstrated by faith something that nobody in Israel had yet accomplished. He had believed in the sovereignty of the Lord Jesus Christ and his ability to speak a miracle into existence. He, being a heathen Roman officer, had great faith.
You must remember that your family history, like the centurion’s, does not determine or hinder your spirituality. Even your past–whether it be good or bad–does not determine your current spiritual state. Your spiritual condition is directly related to your faith. However, sin can cause you to walk in the flesh which reduces your ability to trust God, but your history does not determine your future.
As you venture forward in your walk with the Lord, live beyond your circumstances and believe in him.
