Verse by verse exposition through the book of Hebrews. (Sermon also includes the reading and exhortation from the Lord's Table liturgy) Heb 12:15 looking carefully lest anyone fall short of the grace of God; lest any root of bitterness springing up cause trouble, and by this many become defiled; 16 lest there be any fornicator or profane person like Esau, who for one morsel of food sold his birthright. 17 For you know that afterward, when he wanted to inherit the blessing, he was rejected, for he found no place for repentance, though he sought it diligently with tears. Deut 29:18 so that there may not be among you man or woman or family or tribe, whose heart turns away today from the Lord our God, to go and serve the gods of these nations, and that there may not be among you a root bearing bitterness or wormwood; 19 and so it may not happen, when he hears the words of this curse, that he blesses himself in his heart, saying, 'I shall have peace, even though I follow the dictates of my heart'—as though the drunkard could be included with the sober.
