Just think, you can do anything you want for the rest of your life and your irrevocable ticket to heaven was paid for with the blood of Christ almost 2000 years ago. The primary error here, has its roots in the fact that protestant churches are built on the wrong foundation, therefore no matter how much work they do to their church, it will not help if the foundation is faulty. These verses are all good, but the foundation upon which the interpretation of them is built, is faulty. The fault lies in the fact that there are two very different kinds of salvation, not one. We have to ' Hear' His word, AND we have to 'Believe' in Him.
Fundamentalists accept the second part and ignore the first.
Those other verses I quoted are from the first kind, or ' Objective Salvation. Jesus Christ did in fact redeem all men by his sacrifice on the cross. He paid for the sins of all mankind, past, present, and future with His blood. He did His part, but He did not buy each of us a guaranteed foolproof, irrevocable 'ticket' to Heaven as some churches teach. He redeemed us and opened the gates of Heaven and gave us free will to decide for ourselves where we will spend eternity.
