Would you like to make a difference? These ten boys grew up to do just that - but first they had to change the church. How did God change them? Augustine discovered the love of God and changed the way we think; Knox focused on God's word and told his country the truth; Luther rediscovered God's truth and gave it to ordinary people; Calvin realized that salvation was a gift from God and not a reward for what he did; Tyndale longed to print the Bible in a language that everyone would understand; Latimer urged people to read the Bible for themselves and made enemies as a result; Hus taught that God is in charge of the church and the world; Zwingli challenged people to obey God's word in every area of their lives; Chalmers called the church to show Christ's compassion to the poor and Shaftesbury pushed the church into making Christ's love a living reality for everyone.
