Often, the Bible uses evidential arguments. For example, when scripture states in Psalm 19 that the heavens declare the glory of God, it is denoting how God’s glory is manifested in the natural world. It is proven by nature itself. Evidence and proof are everywhere around us. If you offer an evidential assertion, you should have real evidence to posit such.Equally, there is no amount of evidence that is adequate in and of itself to persuade a non-believer of the truth of Jesus Christ. Prayer must be undertaken and the gospel must be presented, but God’s grace is the ultimate means for salvation of a soul.
At night, atheists find themselves looking out at the starry hosts spangled against the dark canvass of the night and declare that it was all just an accident. They do not see design where design clearly resides. The mathematical precision necessary for the running of the planets to and fro was not designed. All the precision came from chaos and blind chance. They have blind faith in scientism as they suppress the truth in unrighteousness. In actuality, they know that God designed the cosmos, but they do not want to believe it.
Logically, there cannot be any true atheists. For one to propose that God does not exist, anywhere at any time, one would have to know all things, and be omnipresent, eternal, and infinite. That would make you God.
