1 John 4:18

There is no fear in love - Love is not an affection which produces fear. In the love which we have for a parent, a child, a friend, there is no fear. If a man had perfect love to God, he would have no fear of anything - for what would he have to dread? He would have no fear of death, for he would have nothing to dread beyond the grave. It is guilt that makes people fear what is to come; but he whose sins are pardoned, and whose heart is filled with the love of God, has nothing to dread in this world or the world to come. The angels in heaven, who have always loved God and one another, have no fear, for they have nothing to dread in the future; the redeemed in heaven, rescued from all danger, and filled with the love of God, have nothing to dread; and as far as that same loves operates on earth, it delivers the soul now from all apprehension of what is to come.

But perfect love casteth out fear - That is, love that is complete, or that is allowed to exert its proper influence on the soul. As far as it exists, its tendency is to deliver the mind from alarms. If it should exist in any soul in an absolutely perfect state, that soul would be entirely free from all dread in regard to the future.

Because fear hath torment - It is a painful and distressing emotion. Thus men suffer from the fear of poverty, of losses, of bereavement, of sickness, of death, and of future woe. From all these distressing apprehensions, that love of God which furnishes an evidence of true piety delivers us.

He that feareth, is not made perfect in love - He about whose mind there lingers the apprehension of future wrath, shows that love in his soul has not accomplished its full work. Perhaps it never will on any soul until we reach the heavenly world, though there are many minds so full of love to God, as to be prevailingly delivered from fear.
