'The fear of our God' is not the servile dread of a slave toward a master but the loving respect of a child toward a parent. To fear the Lord means to seek to glorify God in everything we do. It means listening to His Word, honoring it, and obeying it. 'The remarkable thing about fearing God,' wrote Oswald Chambers, 'is that when you fear God, you fear nothing else, whereas if you do not fear God, you fear everything else.' Because Nehemiah's life was motivated by the fear of the Lord (Neh. 5:15), he did not fear what the enemy might do (vv. 14, 19). The fear of the Lord moved Nehemiah to be a faithful servant of the Lord.
To walk in the fear of God, of course, means to walk by faith, trusting God to deal with your enemies and one day balance the accounts. It means claiming Matthew 6:33 and having the right priorities in life. 'The fear of the Lord leads to life, and he who has it will abide in satisfaction; he will not be visited with evil' (Prov. 19:23).
Christ says: "Seek first His kingdom and His righteousness, and all these things will be given to you as well" (Matt. 6:33, niv).
