Here we see a statement by the Psalmist David to all those people who fear God, who follow the right path regardless of the obstacles, they will be blessed by God.
Behold, that thus shall the man be blessed that feareth the Lord.
The fear of God will lead us every day to follow the Lord, to love His way, to practice justice, He will take care of us when we walk on dangerous paths, He will separate the enemy from our ways, because the fear of God makes us stand firm in front of Him.
When we walk under the Lord’s guidance, it is because we obey Him and we decide that the way of the Lord is right for humanity. Something that this man named David had was that everything he said, he said it for sure.
