OK. How many of the commandments do you keep all the time?To believe is to obey.
If the answer is "none of them all the time, but some of them most of the time", then you've just condemned yourself.
If the answer is "all of them all the time", well, we all know what that means. Just another sin. Called lying.
To believe is to TRUST fully in the work of Christ. It is to REJECT one's own work.
