The very first problem is what is your standard that you live by? If is anything other than the scripture, finding the answer will be often hard. Books are written about Jesus or about the Bible. This may in some ways be encouraging but it is not the source material one really needs. Who but God could tell us about Himself, His Son, the Spirit and the work of redemption (2 Tim. 3:16). John informs us that everything Jesus did or taught was not recorded. He adds there is sufficient enough evidence in what has been recorded to bring one to faith in Jesus as being the Christ (John 20:30,31). If one does not accept the evidence they can not be converted to Christ.
We have over the years seen some good books produce on apologetics and the evidences of the world around us (Psa. 19:1-3). For example a person who buys into the false doctrine of “global warming” or “climate change” would never accept the power of Genesis 8:22. As long as the world stands, night and day will always be with us. If one is in the position of trying to maintain liberal thinking, no matter what God says, people will not change. The reality is the evidence is not that hard to understand nor come by. The problem is once you accept the truth from God, it requires a change in thinking about the world around us (I John 2:15,16).
Yes the world is made up of invisible things to the naked eye. What if a person never bothers to consider where we came from or where we are going. To listen to arguments from scripture disturbs the life they are living and they have no desire to change. Our faith is based on evidence both from the written Word and the physical world around us (Heb. 11:1). The ultimate standard is the Word itself. What if in the physical world we never find Noah’s ark? We know there was an ark because God says so. If Jesus is God, then we must obey Him. If He is not God then live your life however you chose. Jesus spoke of men dying in their sin for unbelief (John 8:24). Be honest, accept the evidence and live.
