Stephen Olford comments on this text:
What an encouraging verse this is! Solomon says, “The fear of man brings a snare” (Prov. 29:25). How true this is! Bondage to men because of fear is one of the greatest snares in a Christian's life. But this need not be if the heart is in the experience of this verse: “The Lord is my helper, I will not fear. What can man do to me?” (Heb. 13:6).
O, that I may enter into the practical experience of this verse; that I may be delivered from the fear of man. It would almost seem that Timothy suffered from the same things, for Paul writes to him, “Stir up the gift of God… . For God has not given us a spirit of fear, but of power and of love and of a sound mind. Therefore do not be ashamed of the testimony of our Lord” (2 Tim. 1:6-8). (According to Your Word, pp.216-217)
As I think of those who preach the Gospel, there will frequently be the roar of the devil, as a lion, seeking to terrify us. “If you say that, then so-and-so will be angry. Deal with that topic and this family will leave the church or that businessman will withhold his giving.” There will be those who seek to intimidate the pastor, bully him and threaten him.
We cannot cave and compromise. Our Helper is with us. Fear God and we need fear nothing or no one else!
