It is not the will
Of my Father in heaven
That one of these little ones
Should be lost.”
οὕτως οὐκ ἔστιν θέλημα ἔμπροσθεν τοῦ Πατρὸς ὑμῶν τοῦ ἐν οὐρανοῖς ἵνα ἀπόληται ἓν τῶν μικρῶν τούτων.
This explanation of the lost sheep parable can also be found in Luke, chapter 15:7, with some minor changes, as Luke has this lost sheep as a repentant sinner. Jesus explained that it was not the will of his heavenly Father (οὕτως οὐκ ἔστιν θέλημα ἔμπροσθεν τοῦ Πατρὸς ὑμῶν τοῦ ἐν οὐρανοῖς) that these little ones should be lost or perish (ἵνα ἀπόληται ἓν τῶν μικρῶν τούτων). Thus, this was the simple straightforward explanation. The heavenly Father did not want to lose anyone, just like the good shepherd did not want to lose one of his lost sheep.
