The Holy Bible is the Living Word. It is the Logos. It is the inerrant Word of God. In it you will find that you are chosen. A royal priesthood. A brother or sister in Christ Jesus. God made a covenant with Abram many many years ago. That can be studied in the Old Testament. The New Testament brought us His son to die for us that we might have life and have it more abundant. He died in our place. He carried our sins to the cross. He sits at the right hand of the Father in heaven. We can study the Bible a whole life time and never know all the answers. It takes but a moment to know the Son and through Him to know the Father. You are chosen. Follow Him.
