Of course, a youth who is baptized has made a solemn dedication to Jehovah. That dedication is a promise to love God and to put his will above everything else.
إِذَا كَانَ وَلَدُكَ مُعْتَمِدًا ،‏ فَهٰذَا يَعْنِي أَنَّهُ نَذَرَ حَيَاتَهُ لِيَهْوَهَ ،‏ أَيْ وَعَدَهُ بِأَنْ يُحِبَّهُ وَيَضَعَ مَشِيئَتَهُ أَوَّلًا فِي حَيَاتِهِ .‏ ‏
