IV Maccabees 13:15

15 for great is the trial of soul and danger of eternal torment laid up for those who transgress the commandment of God.

IV Maccabees 13:15 In-Context

13 And one and all, looking on each other serene and confident, said, Let us sacrifice with all our heart our souls to God who gave them, and employ our bodies for the keeping of the law.
14 Let us not fear him who thinketh he killeth;
15 for great is the trial of soul and danger of eternal torment laid up for those who transgress the commandment of God.
16 Let us arm ourselves, therefore, in the abnegation of the divine reasoning.
17 If we suffer thus, Abraham, and Isaac, and Jacob will receive us, and all the fathers will commend us.
