We learn in Romans 1:19,20 that nature itself is a witness to God’s existence and man is left without excuse.  Learning from the case of Cornelius in Acts 10, we saw that if someone really wants to know the Lord, He will make sure someone tells them how to be saved.  In order to be saved, one has to hear and believe the Gospel.  (Read John 14:6.)  We take comfort in Genesis 18:25 – “Shall not the Judge of all the earth do right?”  The Lord will do the right thing.
