Expositor's Bible Commentary Commentary Matthew 10:30

"but the very hairs of your head are all numbered." — Matthew 10:30 (ASV)

The third reason for not being afraid is an a fortiori argument : If God’s providence is so all-embracing that not even a sparrow drops from the sky apart from the will of God, cannot that same God be trusted to extend his providence over Jesus’ disciples? “Your Father” adds a piquant touch: this God of all providence is the disciples’ Father. God’s sovereignty is not limited only to life-and-death issues; even the hairs of our heads are counted. Jesus’ third argument against fear is thus the opposite of what is commonly advanced. Some say that God cares about the big things but not about little details. But Jesus says that God’s sovereignty over the tiniest detail should give us confidence that he also superintends the larger matters.
