Everyone who makes a dedication to Jehovah has first to “prove ” to himself what is“ the good and acceptable and perfect will of God. ”
كُلُّ مَنْ يَنْذُرُ نَفْسَهُ لِيَهْوَه عَلَيْهِ أَوَّلًا أَنْ ‹ يَتَبَيَّنَ بِٱلِٱخْتِبَارِ › مَا هِيَ « مَشِيئَةُ ٱللهِ ٱلصَّالِحَةُ ٱلْمَقْبُولَةُ ٱلْكَامِلَةُ » .‏
