Psalms 33:8 (KJV) Let all the earth fear the LORD: let all the inhabitants of the world stand in awe of him.
9 For he spake, and it was done; he commanded, and it stood fast.
10 The LORD bringeth the counsel of the heathen to nought: he maketh the devices of the people of none effect. note
11 The counsel of the LORD standeth for ever, the thoughts of his heart to all generations. note
12 Blessed is the nation whose God is the LORD; and the people whom he hath chosen for his own inheritance.
Verse 20 says in effect that the counsel and devices of our enemies will not work because Christ won’t allow them to work. This aught to give a measure of peace to those who love and obey King Jesus. Walk in Ever Increasing Boldness!
