Romans 1:21-23 KJV
[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. [22] Professing themselves to be wise, they became fools, [23] And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.

In the beginning, God created all things.
There is only one beginning, and there is only one God.

He is a fool who says there is no God.
He is a fool who says God did not create all things.
He is a fool who says God is not Lord of the seventh day sabbath.

Luke 12:20 KJV
[20] But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided?

Romans 1:18-20 KJV
[18] For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; [19] Because that which may be known of God is manifest in them; for God hath shewed it unto them. [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:

2 Timothy 3:16-17 KJV
[16] All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: [17] That the man of God may be perfect, throughly furnished unto all good works.
