But God does give us evidence and reasons to believe. It is not blind faith. But it’s also not absolute proof in a philosophical sense. The Bible also uses the word “understood” when teaching the concept that things are so clearly understood by people about God that they have no excuse.
God says there is sufficient evidence to give an understanding of Himself. There are at least three basic ways the Bible discusses that bring about this understanding that can lead to belief or suppression of the truth leading to unbelief.
1. The Testimony of Creation
Psalm 19:1-4
1The heavens declare the glory of God;
the skies proclaim the work of His hands.
2Day after day they pour forth speech;
night after night they reveal knowledge.
3Without speech or language,
without a sound to be heard,
4their voice has gone out into all the earth,
their words to the ends of the world.
Rom 1:19-20
19For what may be known about God is plain to them, because God has made it plain to them.
20For since the creation of the world God’s invisible qualities, His eternal power and divine nature, have been clearly seen,
being understood from His workmanship, so that men are without excuse.
Basically, from God’s perspective, the evidence is so plain that you have no excuse if you don’t see it. This is not blind faith.
God shows people that He exists.
Rom 1:18 says people suppress this knowledge because of their sin. They don’t want it to be true because of their sin.
18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness.
The typical way people suppress this knowledge has been to turn to idolatry. Idolatry was universal until recent times when it has been replaced by evolutionary theory. See Romans 1.
It seems that God has even predicted that in the last days people would reject and mock Him and the promise of Jesus return because of evolutionary theory.
2 Peter 3:4
They will say, “Where is the promise of his coming? For ever since the fathers fell asleep, all things are continuing as they were from the beginning of creation.”
Could this verse really have been a prediction that evolutionists would teach natural selection? Does it tell us that evolutionists would believe that all things have continued without intervention by God or any beings, but natural processes only? The Big Bang is certainly the evolutionists version of creation. It would appear that saying the following would not be inconsistent with the meaning of this verse:
They will say, "Where is the promise of His coming? For all things continue since the Big Bang, through the time of our ancestors, and into the present, by natural processes, without Divine intervention."
(My own revision of the verse).
The timing of this will be in the last days.
2. The Testimony of Prophecy Fulfilled
This brings me to the second way that God has provided us with evidence for belief, and that is through prophecies fulfilled. Many times in the Bible God says that prophecy is given so that we can know that the Lord is God, or so that we can believe. Jesus even told his disciples, “I have told you now before it happens, so that when it does happen you will believe.”
The Bible is a big book. Scholars generally say that over ¼ of it was prophetic when it was written. Much of it has already been fulfilled. Prophecies would often be given in one book of the Bible and then the fulfillment confirmed by other authors in later books. There are still many prophecies that apply to the future and seem to be extremely relevant to the time period we are in, based off of the many passages of Israel’s return to her homeland and the events described in Ezekiel 37-39.
Ezekiel 39:28, 29
“...then they will know that I am the LORD their God, for though I sent them into exile among the nations, I will gather them to their own land, not leaving any behind. I will no longer hide my face from them, for I will pour out my Spirit on the people of Israel, declares the Sovereign LORD.” Ezekiel 39:28, 29
3. The Testimony of Direct Revelation of God
Direct revelation was sometimes given to prophets during Old Testament times. Some of these messages have been recorded for us in the Old Testament.
In several places parts of the New Testament also claim direct revelation or guidance from God.
There is also the work of the Holy Spirit in an unbeliever’s heart to reveal the validity of the message of the Bible, see John 3:8. Jesus also described the work of the Holy Spirit like this,
And when He has come, He will convict the world of sin, and of righteousness, and of judgment. John 16:8
There is a conviction that can come, as described in John 16:8, from the Holy Spirit, that does not exist in any other religion. I have experienced this myself many times. Here are two passages that I think do a good job of showing what I mean:
Isaiah 6:5 shows the response Isaiah had to seeing God:
Then I said: "Woe is me, for I am ruined, because I am a man of unclean lips dwelling among a people of unclean lips; for my eyes have seen the King, the LORD of Hosts."
Luke 5:8 tells Peter’s reaction to a miracle Jesus did that Peter had doubted beforehand. Peter suddenly realized some of Jesus’ majesty and power.
When Simon Peter saw this, he fell at Jesus’ knees and said, “Go away from me, Lord; I am a sinful man!”
Idolatry and other religions do not teach of a good and holy God who is very offended by our sin, yet still offers reconciliation without any personal merit. This is unique to Christianity.
The message of the gospel speaks to our hearts. We know we are guilty, and when we come to realize a glimpse of the absolute perfection of God’s character and how fall short we fall, this should drive us to pursue reconciliation with God through the salvation He promises through simple faith and repentance toward Jesus. However, we are given a choice to respond correctly or to continue in our own ways.
The main reason people do not want to believe this is because, as Jesus put it, “men loved darkness rather than light, because their deeds were evil.” John 3:19
