Ephesians 2:8, 9
"For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast."
In other words...
Through God's Grace He saves our soul ~but~ ONLY BY FAITH! WE can NOT save ourselves. We can't EARN our spot in heaven. Being a 'good' person won't get us there.
The only thing that gets us to heaven is having faith in Jesus. Jesus said this, "I am the way and the truth and the life. No one comes to the Father except through me." John 14:6
