And if we choose wrong based on our finite understanding of things.... we are lost?
Alright. I'll take that under advisement.
Choosing to believe God or His Son is never wrong, according to Scriptures.
Eve wasn't lost until she took directions from someone other than God. Anyone who reads the account can see this, but it's a choice we make whether to believe it or not. And yes, if you choose to reject God's Word, and choose to listen to another voice, you are lost. That's the whole point.
