Deuteronomy 29:29 [KJV] The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children for ever, that we may do all the words of this law.
[Deuteronomy 29:29] speaks of the sufficiency of God’s revelation and affirms that he will reveal to his people whatever they need to know. This understanding should give them rest in knowing that he is at work and should help them trust in his sovereign ways. Their focus should be obedience to the word that God reveals.
