He said, “If you listen carefully to the voice of the LORD your God and do what is right in his eyes, if you pay attention to his commands and keep all his decrees, I will not bring on you any of the diseases I brought on the Egyptians, for I am the LORD, who heals you.”

This day I call heaven and earth as witnesses against you that I have set before you life and death, blessings and curses.

For the LORD is your life, and he will give you many years in the land he swore to give to your fathers, Abraham, Isaac and Jacob.

Psalm 103 Of David.

He said to them, “Go into all the world and preach the good news to all creation. 16) Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17) And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 8) they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring – not only to those who are of the law but also to those who are of the faith of Abraham. He is the father of us all. 17) As it is written: “I have made you a father of many nations.” He is our father in the sight of God, in whom he believed – the God who gives life to the dead and calls things that are not as though they were. 18) Against all hope, Abraham in hope believed and so became the father of many nations, just as it had been said to him, “So shall your offspring be.” 19) Without weakening in his faith, he faced the fact that his body was as good as dead – since he was about a hundred years old – and that Sarah’s womb was also dead. 20 ) Yet he did not waver through unbelief regarding the promise of God, but was strengthened in his faith and gave glory to God, 21) being fully persuaded that God had power to do what he had promised.
