In his letter to the Hebrews, the apostle Paul wrote: “The word of God is alive and exerts power and is sharper than any two - edged sword and pierces even to the dividing of soul and spirit, and of joints and their marrow, and is able to discern thoughts and intentions of the heart. ”
يَقُولُ :‏ « كَانَتْ [كَلِمَةُ ٱللهِ] فِي قَلْبِي كَنَارٍ مُتَّقِدَةٍ قَدْ حُبِسَتْ فِي عِظَامِي ،‏ فَتَعِبْتُ مِنَ ٱلْإِمْسَاكِ » .‏
