5 Every word of God proves true; he is a shield to those who take refuge in him. 6 Do not add to his words, lest he rebuke you and you be found a liar. Proverbs 30:5-6
The Clarity of God's Word
11 “For this commandment that I command you today is not too hard for you, neither is it far off. 12 It is not in heaven, that you should say, ‘Who will ascend to heaven for us and bring it to us, that we may hear it and do it?’ 13 Neither is it beyond the sea, that you should say, ‘Who will go over the sea for us and bring it to us, that we may hear it and do it?’ 14 But the word is very near you. It is in your mouth and in your heart, so that you can do it.
Deuteronomy 30:11-14
The Authority of God's Word
