The first step in knowing God is to find out more about Him. Read Isaiah 53, then read the New Testament books of John and Romans. I know that is a lot of reading but if you really want to investigate and learn about God, those are the books you should begin with. After you have read them, go back to the book of Genesis and read through as much of the Bible as you can. Some books are a little hard to read with the rules of sacrifices and the genealogies that are part of many books.
The more you learn about God, the more you will come to know Him, and knowing Him will bring you to love Him and you will want to obey His commandments and live according to His ways. By doing this you will become a disciple of His and you will want to spread His message to those around you. Being in a relationship with God gives your life meaning and a purpose that you can’t get from anything else on Earth. Seek Him and come to know Him and your life will never be the same. It will be the best life you could ever have.
