أَلَسْتُمْ تَعْلَمُونَ أَنَّ الَّذِي تُقَدِّمُونَ ذَوَاتِكُمْ لَهُ عَبِيدًا لِلطَّاعَةِ،
أَنْتُمْ عَبِيدٌ لِلَّذِي تُطِيعُونَهُ: إِمَّا لِلْخَطِيَّةِ لِلْمَوْتِ أَوْ لِلطَّاعَةِ لِلْبِرِّ؟
(رو٦ :١٦ )

Don't you know that when you offer yourselves to someone to obey him as slaves, you are slaves to the one whom you obey--whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?

(Romans 6:16, NIV)
