It is of utmost importance that we understand what the heart represents because the Bible states that we need to safeguard it. ​ — Read Proverbs 4: 23.
وَمِنَ ٱلْمُهِمِّ جِدًّا أَنْ نَعْرِفَ مَا يُمَثِّلُهُ هذَا ٱلْعُضْوُ لِأَنَّ كَلِمَةَ ٱللهِ تَحُثُّنَا أَنْ نَصُونَهُ .‏ —‏ اِقْرَأْ امثال ٤ :‏ ٢٣‏ .‏
