The holy righteous John of Kronstadt (1829–1908) was called “the hero of the spirit.” To monitor his inner life, the righteous man kept a daily diary, in which he entered his innermost thoughts and prayers to God. These diaries, included in the now famous book “My Life in Christ,” are our invaluable asset. Father John had the greatest gift of prayer and deeply believed that the Lord is as close to a Christian believer as his own body and heart. Published from the book: Holy Righteous John of Kronstadt.
