I am 80 and have been a fanatical eternal security teaching Baptist until 4 years ago and am now a Free Will Baptist.
The reason I changed was that ES Baptists totally ignore God's inspired Greek present participles behind "eth" and "es" verbs like "believe," "abide" and "overcome." It is wrong to change God's Word from a "continuous," or "habitual", or "regularly" meaning into a "one-time profession of faith" which requires a past-tense aorist verb. Greek teachers should be ashamed for allowing this to occur.
Hi Russel, thanks for the excellent study question. Does the fact that those saved "continuously believe" mean we must "continually believe" in order to remain saved?
I say NO.
In Post #7, you address John 10:27, which has "hear" and "follow" in the present tense. I agree, those born anew sometime in their past are said to in the present still hear and follow, thus they continue their adherence to their faith in God.
Next, in post #8, you address John 3:16, which as "believes" or "is believing" as the condition of those who will not perish but have everlasting life.
Again, I agree, that is the characteristic of those who have become His sheep, born anew children of God.
Which brings us to post #9, and Jesus praying for those who believe because of His disciples word. I believe the idea extends past the present, and to everyone, such as me, who will believe in the future when viewed from the time of His prayer. Thus, the idea is at the time of being given to Christ, they will be, in that present time, believing, not had believed, or will believe.
Next you mention John 6:40 which as those who "behold the Son and believes (present tense) into Him will have everlasting life and will be raised on the last day. So once again we have some who is believing at the time of salvation and then continues be believe as solid doctrine.
Continuing with post 10, you address 1 John 5:13 which says those who are believing may know they have everlasting life. Here again we have the characteristic of those born anew of continuous belief or faith. In 1 John 5:1 we have those who are believing that Jesus is the Christ have been and are continuing to be born of God. We can, I believe reverse the logic ans conclude those born anew will continuous believe or have faith.
Next, post #11, you address Hebrews 6:4-6 with the apparent assumption those in view were born anew. I hold a different view. So setting that aside, let us continue with the characteristic of continuous belief or faith.
Finally you mention Romans 4:5 which says those who believe (present tense) on Him who justified, their faith is credited as righteousness. So again, when a person is believing, God takes action and subsequently, they continue to believe or have faith.
No one should dispute that analysis. However, if when a person is born anew, their faith is protected by the power of God, it would be impossible to anyone born anew to lose or destroy that faith.
Which brings me to my rebuttal (excepting Hebrews 6:4-6) of the contention that a born anew believer can somehow lose or destroy the faith they had when God credited it as righteousness. See 1 Peter 1:3-5. I believe when we are born anew, God protects our faith such that we will receive our inheritance, our salvation, our everlasting life.
