How do we know there is a God? -
Rom 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
Rom 1:19 Because that which may be known of God is manifest in them; for God hath shewed it unto them.
Rom 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
Rom 1:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
Rom 1:24 Wherefore God also gave them up to uncleanness through the lusts of their own hearts, to dishonour their own bodies between themselves:
Rom 1:26 For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
Rom 1:27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet.
Rom 1: 28 And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;
Rom 1:29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
Rom 1:30 Backbiters, haters of God, despite ful, proud, boasters, inventors of evil things, disobedient to parents,
Rom 1:31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
Rom 1: 32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
Deu 4: 6 Keep therefore the commandments and do them; for this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes, and say, Surely this great nation is a wise and understanding people.
Deu 4:7 For what nation is there so great, who hath God so nigh unto them, as the LORD our God is in all things that we call upon him for?
Deu 4:8 And what nation is there so great, that hath statutes and judgments so righteous as all this law, which I set before you this day?
