It is true; No one can “prove” to you there is a God.
But have you considered the reasonableness of it?
The man of the world says “Show me, and I’ll believe.”
God says “Believe what little you know and I’ll show you more.”
God loves faith! The Bible says:
“But without faith it is impossible to please Him;
for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him.”
Hebrews 11:6
Yes, God loves faith.
Not blind faith, or faith that makes up its own story to believe, but faith in what He reveals.
Not to everyone, but to those who understand this very reasonable truth:
that if God can create, He can communicate.
Even more basic, God has given everyone 2 witnesses of His existence:
Something inside them ( the CONSCIENCE ) Romans 1:19; 2:15
Something outside them ( the CREATION ) Romans 1:20
Both the spiritual dimension in human beings and the orderly creation in the universe provide some evidence for the existence of an intelligent Creator
No wonder a famous king in history wrote:
“The fool hath said in his heart, There is no God.” Psalm 14:1
No, no one can “prove” to you there is a God.
That would remove the element of faith, which God loves.
But are you sure that the evidence better supports the position that all that you see and know arose by chance?
