Paul did not dwell on the wrong course he had pursued in Judaism. Instead, he concentrated all his energies on qualifying himself for the future prize of eternal life. All of us can apply the principle behind Paul’s words.
فَهُوَ لَمْ يَغْرَقْ فِي ٱلتَّفْكِيرِ فِي مَسْلَكِهِ ٱلْخَاطِئِ ٱلَّذِي ٱتَّبَعَهُ فِي ٱلدِّيَانَةِ ٱلْيَهُودِيَّةِ ،‏ بَلْ سَعَى بِكُلِّ طَاقَتِهِ لِيَبْقَى أَمِينًا كَيْ يَنَالَ جَائِزَةَ ٱلْحَيَاةِ ٱلْأَبَدِيَّةِ .‏
