Well, I can only do my best.
Search for truth and understanding with an open mind and heart.
If Satan is stopping me from being convinced, then is it right for God to punish me?
Why doesn't God stop Satan from messing with people?
Is it because he can't (not powerful enough) or because he doesnt want to (perhaps he's busy?..)
The Bible states a problem, man is and has sinned and cannot acquire eternal life by any of their own efforts. That has separated man from God. But God has provided a way back, but just one single way. That way is through faith in The Messiah, believe that Jesus is the promised Messiah from the prophecies of the Tanakh and trust in The Messiah for God's free gift of Eternal Life.
You may be like some who Jesus is addressing in these verses.
Do not labor for the food which perishes, but for the food which endures to everlasting life, which the Son of Man will give you, because God the Father has set His seal on Him.”
Then they said to Him, “What shall we do, that we may work the works of God?”
Jesus answered and said to them, “This is the work of God, that you believe in Him whom He sent.”
What that is saying basically is, have you ever heard where some one learns something. Say a method of landscape oil painting, then they are exposed to a better way. Many times before they embrace this new way of painting and learn from it. They have to work out the old way of thinking from their old way of painting to be able to finally understand and see the new method.
In a way that is the case of many people they have been blinded by different theologies and can not see that God simply offers eternal life as a free gift to anyone who simply trust in The Messiah for this free gift. It is not about going to church or joining church or following some teachings of some denomination, etc... it is just like how this verse states.
You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me. But you are not willing to come to Me that you may have life.
Read the Gospel of John the only book in the Bible whose stated purpose for being written is to tell people how to have life (eternal life).
And truly Jesus did many other signs in the presence of His disciples, which are not written in this book; but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name.
