Wondering,
Your concern is justified with the OSAS promoters. I consider that a biblical understanding is represented by the language of 'perseverance of the saints'. Believers will continue to believe, i.e. persevere. Here's one verse that deals specifically with this issue:
The meaning of 1 John 5:13 (ESV)
What does
1 John 5:13 (ESV) teach? The verse states, ‘I write [Gk aorist tense] these things to you who believe [Gk present tense] in the name of the Son of God that you may know [Gk perfect tense] that you have [Gk present tense] eternal life.
The aorist tense is point action
. The present tense refers to continuing action in the present time. The perfect tense refers to an action in the past with continuing results. In Dana & Mantey’s advanced Greek text, they explain that there are ‘two fundamental ways of viewing action’ for Greek tenses. ‘It may be contemplated in single perspective, as a point, which we may call
punctiliar action…; or it may be regarded as in progress, as a line, and this we may call linear action…. The perfect tense is a combination of these two ideas: it looks in perspective at the action, and regards the results of the action as continuing to exist; that is, in progress at a given point. Hence the perfect has both elements, linear and punctiliar. The aorist may be represented by a dot (
), the present by a line (————), and the perfect by the combination of the two (
————-) [Dana & Mantey 1955:179].
Therefore, the meaning of
1 John 5:13 (ESV) is NOT that somebody believed in the past and thus is guaranteed eternal security for salvation, no matter what he or she does after saying ‘yes’ to Jesus. The meaning is that it is written to those ‘who continue to believe in the name of the Son of God so that you may continue to have the result of knowing that you are continuing to have eternal life’. So, perseverance of the saints is better language than eternal security OSAS, based on this verse,
1 John 5:13 (ESV). Christian believers are those who continue to believe to the end of their lives.
Why is that the case? It is because the original Greek language of the text affirms that the Christians who continue to believe in the name of the Son of God will know that they continue to have eternal life. Thus, eternal life is guaranteed to those who persevere in the faith – they continue to believe (taken from my article,
Continue in the faith to guarantee eternal life)
