First is creation: people can perceive that everything made and all that sustains their day-to-day lives must have come from a marvelous and powerful Creator.
For the invisible things of Him since the creation of the world
are clearly seen, being perceived through the things that are made, even His everlasting power and divinity;
that they may be without excuse.
Romans 1:20 HNV
Second is conscience, allowing people to realize that some of what we observe around us—things like sorrow, suffering, and death—are not as they ought to be. This suggests a standard of right and wrong, of good and evil, and hints that it originated from Someone other than us.
Since they thought it foolish to acknowledge God,
He abandoned them to their foolish thinking
and let them do things that should never be done.
Romans 1:28 NLT
Third is the person and work of Christ, who as God’s perfect image in human form taught us about who God is and accomplished salvation from sin and death for us when we were helpless to do anything for ourselves.
Hath in these last days spoken unto us by His Son,....
Who being the brightness of His glory,
and the express image of His person,...
Hebrews 1:2,3
And finally, God reveals Himself in Scripture, describing His plan for all of creation throughout the course of history, until things are once again restored and His children can live together with Him in harmony, fullness, and perfection.
Blessed is he that readeth,
and they that hear the words of this prophecy,
and keep those things which are written therein:
Revelation 1:3."
AIG
