Certainly it's a free ride. It's a gift.
The sacrifice was enough to cleanse us from all our sin and put us in Christ. Our life is hidden with Christ in God. We ARE heirs with Him already seated in the heavenly realms.
If you trust in Christ completely for salvation, you can be in that position as well. If you want your good works to save you, well good luck with that. God will judge you on that but don't forget that the wages of sin is death.
I am always intrigued when a Catholic spouts Mormon doctrine.
As metmom said, it is a gift, if works were required then it is no longer a gift. If works are needed than grace is no longer grace. Salvation (entrance into Heaven) is by faith. Belief is not a ‘free ride’, but all we have to do is believe. Not ‘do our part’. That is unbiblical.
Since you bragged earlier about not needing to memorize scripture, let me help you out here...Romans 11:6 - And if by grace, then it is no longer by works; if it were, grace would no longer be grace.
Or do you not accept the teaching of St. Paul?
