“The fear of the Lord is wisdom, because it sets a person in communion with God and sets him on the path to the fullness of knowledge that will dawn in Christ. Indeed, the fear of the Lord is granted to a sinful person only for the sake of Christ. God acts in mercy towards people in Old Testament times by reckoning for their benefit beforehand the grace that will be accomplished in Christ. Even in the Old Testament, godly people experienced beforehand some foretaste of the wisdom of God and the communion with God. The full realization of that communion awaited the coming of Christ. And of course we still await a yet fuller communion with God in the new heavens and the new earth.” (Vern Poythress)
