The first two spiritual laws are that God has a good plan for your life because he loves you and that humans created sin and are separate from God. The last two laws are that sins are forgiven through Jesus Christ and one must have faith in Jesus in order to reach salvation. These are the laws from "The Four Spiritual Laws" by Bill Bright.
The first law of this booklet discusses how there is a divine plan for every life and the ways people can remove the blocks from feeling the love of God. It also talks about how to have an abundant life and what prevents people from doing so.
The second law is about how humans are tainted by sins and that is why they suffer. It describes how sin is what keeps people from knowing what God has planned for them.
The third law talks about the process of forgiving sins through belief in Jesus. The author believes that faith in Jesus is the only way to be cleansed of sins.
The fourth law discusses how the people who believe in Jesus and receive him become children of God. Bill Bright believes that this is the only way to obtain the gifts of God.
