Deuteronomy 4:29-39

But from there you will search again for the LORD your God. And if you search for him with all your heart and soul, you will find him. “In the distant future, when you are suffering all these things, you will finally return to the LORD your God and listen to what he tells you. For the LORD your God is a merciful God; he will not abandon you or destroy you or forget the solemn covenant he made with your ancestors. “Now search all of history, from the time God created people on the earth until now, and search from one end of the heavens to the other. Has anything as great as this ever been seen or heard before? Has any nation ever heard the voice of God speaking from fire—as you did—and survived? Has any other god dared to take a nation for himself out of another nation by means of trials, miraculous signs, wonders, war, a strong hand, a powerful arm, and terrifying acts? Yet that is what the LORD your God did for you in Egypt, right before your eyes. “He showed you these things so you would know that the LORD is God and there is no other. He let you hear his voice from heaven so he could instruct you. He let you see his great fire here on earth so he could speak to you from it. Because he loved your ancestors, he chose to bless their descendants, and he personally brought you out of Egypt with a great display of power. He drove out nations far greater than you, so he could bring you in and give you their land as your special possession, as it is today. “So remember this and keep it firmly in mind: The LORD is God both in heaven and on earth, and there is no other.
