28:13 The philosopher turns aside from the light of salvation, because it puts his proud theories to shame; the worldling refuses to receive it, because it would separate him from his earthly idols. Paul saw that the character of Christ must be understood before men could love Him or view the cross with the eye of faith. Here must begin that study which shall be the science and the song of the redeemed through all eternity. In the light of the cross alone can the true value of the human soul be estimated.
