That's a wonderful verse, and one that gives us all hope, but It helps to put things in context and to remember other verses on the same subject, lest we misunderstand what it means.

For instance, don't forget, among others, "Let every one who names the name of the Lord abstain from wickedness" (2 Tim. 2: 19, NASB).

Also, "What shall we say then? Are we to continue in sin that grace might increase? May it never be!" (Rom 6: 1,2).

Regards,
"John 3: 17"

I don't think you should ignore errors. But you should put them in their place. Take what is good and throw out the rest.

Read this snippet when considering Ellen White and her writings ...

God is not waiting for particular political events to happen before He can come. He is only waiting for the church to be prepared, and when she is ready, He will allow those events prophesied in the Bible to happen. God wanted Christ to come for His church a long time ago, just He planned for the Israelites to go right into the Promised Land. It was only their stubbornness and refusal to believe and obey that kept them out and caused them to die in the wilderness. The same has been keeping the church from entering into the heavenly promised land.

GREAT POINT! I've never though of it that way before! At the same time I think it's not only the church, but the world that is given some time also.
