A friend and I are having an ongoing discussion regarding the question of whether or not when you ask Christ to be your Lord and Savior, whether you are "always saved" from that point onward. I am not a theologian or biblical scholar, but by searching the scriptures, this is what I come up with.
Once you ask the Holy Spirit in your heart, I don't see how you could ever reject Him, but if you look to the scriptures, you can see several examples showing that you could. These have been provided by my pastor:
[We can define] sin as "a willful transgression against a known law of God." With that definition we wouldn't call every time we fall short of the glory of God a sin. There are misjudgments, errors we make, that definitely fall short of the glory of God, but it's not willful rebellion against God. Sin would be those things where we know what God wants and we willfully choose not to do it, or willfully choose to do what He says not to do.With that understanding of sin, we leave intact free will, and with that we conclude, as much as it doesn't seem anyone would ever want to, there will be those that will choose to be involved in sin and thus choose to walk away from their salvation, the same way the prodigal son walked away from his father.
One of the very strong passages of Scripture that shows a person can decide to walk away from Christ is II Peter 2:20-22. It states, "If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ (that sounds like a "saved" person to me) and are again entangled in it and overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them. Of them the proverbs are true: "A dog returns to its vomit," and " A sow that is washed goes back to her wallowing in the mud."
That brings us to the question of Charles Templeton, who was once a bigger evangelist than Billy Graham. (You'll see how this all ties in in a minute.) He rejected Christianity outright and wrote a book called "Farewell to God" which is sold by many humanist and atheistic organizations. In it, Templeton writes:
Why does God's grand design require creatures with teeth designed to crush spines or rend flesh, claws fashioned to seize and tear, venom to paralyze, mouths to suck blood, coils to constrict and smother - even expandable jaws so that prey may be swallowed whole and alive? & Nature is in Tennyson's vivid phrase, "red in tooth and claw," and life is a carnival of blood.
Templeton then concludes:
How could a loving and omnipotent God create such horrors as we have been contemplating?
Templeton misses the whole foundational message in Genesis, wherein we are told God made a perfect world, but now it is cursed and marred by sin, whereby death is the consequence. The Bible tells us that everything, even the ground, was cursed, and that the plants grew thorns! So rather than blaming ourselves for our original sin, Templeton blames God, when he is not to blame.
Templeton was attending Princeton and was swayed by millions of years mentality and eventually lost his religion outright. So was he ever "saved" at all? How many people will not see salvation because of his teachings? And just how important is the issue of Genesis? Well, let's take a look at one more quote to drive the point home. In a letter to Billy Graham, he wrote:
But, Billy, it's simply not possible any longer to believe, for instance, the biblical account of creation. The world wasn't created over a period of days a few thousand years ago; it has evolved over millions of years. It's not a matter of speculation; it's demonstrable fact.
And the door to Biblical inaccuracy was opened, and eventually, over a period of millions of seconds, Charles Templeton, like Charles Darwin, Ted Turner and countless others, abandoned their Christianity on the basis of first abandoning the foundation it rests upon.
