Charles Ellicott Commentary Matthew 10:33

"But whosoever shall deny me before men, him will I also deny before my Father who is in heaven." — Matthew 10:33 (ASV)

Whoever denies me — As with all other eternal laws, the blessing for those who fulfill the conditions has its counterpart of woe for those who do not. To deny Christ on earth by word or deed, to live as if His work were nothing to us, must lead to His denying us in the last great day.
