Happy is the man that fears always: but he that hardens his heart shall fall into mischief.
He is not an unhappy man whose heart is continually governed by this fear. It has a happy influence upon his soul, to guard it from the temptations of Satan and the world, and to keep it close to the Redeemer. It tends not to obstruct but to promote the exercise of faith and hope and joy in the Lord. Thus fear is a fruit of the Holy Spirit, and a blessed means of establishing the heart in the love of God. It is a happy sign of an interest in the everlasting covenant of mercy, and in that special favour of God which is the source of all our joys. But wretched is the man who is not afraid to sin against his Maker and Judge. His heart is hard as the nether millstone.
(George Lawson, D.D.)
