Thirsting Souls Bible Teaching

(1Ti 1:13)  “Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief.” He didn’t believe the Lord Jesus to have been the Christ and thus have risen from the grave. But many, if not most, do believe those things. Still they do not come to Christ. There is a big difference. Why should the Lord continue to offer one mercy who knows the great price so lovingly given so they might be saved?
