“Salvation for all who OBEY Him” (Heb. 5:9)?

How many people die every day? What does that say about our human frailty? What did Paul mean by “I die daily”? Why does Hebrews 5:9 say we’re saved by “obeying” Jesus? If we’re totally forgiven for all sins, why do so many Christians ask God for daily forgiveness? What about 1 John 1:9?
