Is the Doctrine of Eternal Security Scriptural?
Here is some of the Biblical evidence that the belief among many Christians today that once they are saved (born again) they are always saved no matter what they do is not Scriptural. This teaching is an extension of John Calvin's tenet of the perseverance of the saints and while it could be argued that many people under the assumption that it does not matter go on sinning presuming on the grace of God; I propose that it is not Scriptural and indeed practically dangerous and pastorally irresponsible to teach this doctrine. It gives people a false sense of security in abdicating them from any cooperation in their own salvation and personal responsibility to obey God's eternal laws. Is my eternal salvation in heaven with God secured? Yes, as long as I do not separate myself from God through sin. As I’m sure you know, 1 John 5:16 11;17 talks about the “sin unto death,” because it is sin that kills the soul…sin that separates us from Jesus Christ Who is the Way, the Truth, and the Life. So, as long as I do not commit a sin unto death – or what we Catholics would call a “mortal” sin – then, yes, my salvation with God is secured.
Now, you may ask, how exactly is it that we can separate ourselves from Christ? Well, we separate ourselves from Christ by, in essence, not following His teachings. By not doing what He has told us we must do, or doing what He has told us we must not do. For example, Jesus tells us in Matthew 6 that in order to have our sins forgiven, we must forgive the sins of others. If we don’t, then our sins are not forgiven. Can we get into Heaven if our sins are not forgiven? No, we can’t. So, we must forgive the sins of others in order to get into Heaven, in order to not separate ourselves from Christ – that is a plain truth of Scripture. We must also care for our families as we are able. This is very clear in 1 Tim 5:8 where we are told that anyone who does not provide for his family has disowned the faith and is worse than an unbeliever. Someone who is worse than an unbeliever can’t get into Heaven, can they? They have separated themselves from Christ.
Then in John 6, Jesus tells us that we must eat His flesh and drink His blood, or we have no life in us. So, can we be saved if we have no life in us? if we do not eat His flesh and drink His blood, will we get to Heaven? We also have to love our brother. It says so plainly in 1 John 4:20. We also have to seek for glory and honor and immortality by patience in well–doing, according to Rom 2:6–7, in order to have eternal life rendered unto us.
In Hebrews 6:4–6, it tells us we can separate ourselves from Christ through apostasy. In Romans 11:22 it says we will be cut off from Christ if we do not continue in God’s kindness. And, in John 15:1–6, it tells us that we will be cut off from the vine which is Christ if we do not produce good fruit. There is more but that should be sufficient to present the case that no one's place in heaven is guaranteed by Scripture. Do you accept and believe the doctrine of eternal security? If so, on what grounds?
