Sincere faith is the only staircase leading to God, but each person holds the keys to Heaven in their own hands - this is our free will. Every time, faced with a choice of conscience, we either gradually open our soul to Eternity, or, on the contrary, we close it, turning away from God, from people and even from ourselves - the way we hoped to become: honest, unselfish, strong, merciful ... The book “Seven Keys...” are the words of the outstanding theologian and thinker, St. Nicholas of Serbia (1880–1956) about human paths to the Kingdom of God. Simplicity and clarity of thought, combined with the poetry of language, the height of theological thought, the evangelical view of life - all this makes St. Nicholas (Velimirović) close and understandable to every reader.
