God has made various contracts with nations or individuals. However, God s plan, has not changed. Here we are before you in our guilt, though because of it not one of us can stand in your presence. That is why if you die while covered with sin, you are thrown into hell. God often uses every day things to teach us His plan.
Sin is described in terms of being spiritually dirty.
When something is dirty, you wash it to make it clean. Again, sin keeps us from entering the presence of God. We first have to do something about our sin before God can enter. Another misunderstanding is the confusion of what is labeled a sprinkling baptism with an immersion baptism. God has always taught that a person must take a spiritual bath to enter His presence.
