I have a friend at work who I can tell completely craves to have Jesus Christ in his life. What he struggles with is the issue of faith. He wants proof of God’s existence. I have a very hard time explaining why I dont need to physically see God in front of me to believe. I was raised Catholic and honestly have never had serious doubts of his existence. Any advice whatsoever is appreciated.
You could plant some seeds and testify to him by your life. You know what St. francis said )(or was it Augustine?): Always preach the gospel and only when absolutely necessary use words.
We each have to come to God on our own basis so all you could do is help him along.
The most important thing is to know who Jesus is. Was he a good man? Was he a prophet? Was he God?
He should read the New Testament if he’s really interested. After he reads it, ask him this: Was Jesus God OR was he a crazy man? I’ve found this to work well. Jesus leaves us no room but to believe that He is God. Otherwise he was crazy. I mean no disrespect for the Lord, as you must understand. He could not have been merely a good man or a prophet.
Some books:
Proof that Demands a Verdict
Written by an atty who set out to disprove God and ended up being a believer
Mere Christianity by C.S. Lewis
Who Moved the Stone?
Was the resurrection real?
Skeptics Should Consider Christianity - Josh McDowell and Don Stewart
or any of his/their books
Answering the New Atheism - Scott Hahn
Father Spitzer, a priest and pysicist has a great book out on the theories of how the universe began and how God is the cause, but I can’t remember the name.
Hope this helps.
God bless you in your effort

P.S. It never hurts to see if the person believes in an afterlife and what is going to happen to him. In a nice way, of course!
