Studying the lives of people in the Bible can bring hope to believers today. The life of John Mark in the New Testament illustrates the truth that failure is not final for believers.
John Mark was the son of Mary, an affluent godly widow in Jerusalem who allowed believers to meet in her home for prayer.
John Mark likely had contact with many wonderful people who took part in that fellowship. At some point the apostle Peter led him to the Lord, because he later called him his spiritual son.
