There are many mysteries with God. But His reality is plain enough. All anyone must do is open their eyes. The reality is right in front of us.
You cannot hide the truth. God is and God is love.
- God is and God is light.
- Plain enough to see that.
- Jesus came as an act of God’s love and showed us the truth.
Jesus is the Messiah, the one anointed by God to restore us in right standing with God.
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of people who suppress the truth in unrighteousness, 19 because that which is known about God is evident within them; for God made it evident to them. 20 For since the creation of the world His invisible attributes, that is, His eternal power and divine nature, have been clearly perceived, being understood by what has been made, so that they are without excuse. 21 For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their reasonings, and their senseless hearts were darkened. 22 Claiming to be wise, they became fools, 23 and they exchanged the glory of the incorruptible God for an image in the form of corruptible mankind, of birds, four-footed animals, and crawling creatures. 
Human history began with man knowing God. Human history is not the story of a beast that worshiped idols, and then evolved into a man worshiping one God.
- Human history is just the opposite: man began knowing God but turned from the truth and rejected God.
- God revealed Himself to man through creation, the things that He made.
- From the world around him, man knew that there was a God who had the wisdom to plan and the power to create.
Man realized too that this Creator was eternal … “His eternal power and Godhead” (Rom. 1:20), since God could not be created if He is the Creator. These facts about God are not hidden in creation; they are “clearly seen” (Rom. 1:20). “The heavens declare the glory of God, and the firmament shows His handiwork” (Ps. 19:1).
The word translated “hold” in Rom. 1:18 can also be translated “hold down, suppress.” Men knew the truth about God, but they did not allow this truth to work in their lives. They suppressed it in order that they might live their own lives and not be convicted by God’s truth.
The result, of course, was refusing the truth, and then turning the truth into a lie. Finally, man so abandoned the truth that he became like a beast in his thinking and in his living.
Good news: God is God. God has made Himself known to us. We must acknowledge Him and give ourselves over to doing what He wants, not what we want. God is in a good mood, but we should be aware of His wrath. We have no excuse to be ignorant of God and His ways.
