"No one born of God makes a practice of sinning, for God’s seed abides in him, and he cannot keep on sinning because he has been born of God."
1 John 1:9
nothing is untenable within context unless you ignore scriptural context. The NT is VERY clear that rather than there being just two groups - non christian and Christian - there are in fact people who will be among the church but not truly there as full believers. Jesus' parable of the sower makes it clear. some people believe for awhile some people believe for joy but both have no root. Multiple other passages particularly in 1 john indicate that they show themselves as not being part of the saved group when they leave the church. All of which in biblical context indicates Believers don't always translate to saved. Simon of acts 8 in particularly drives this home
"Simon himself believed and was baptized. And he followed Philip everywhere, astonished by the great signs and miracles he saw."
just a few verses later Paul berates him and tells him he isn't even saved and has no part in the Holy Spirit. So of course The NT gives warnings to the church. Why wouldn't the apostles since they knew in every church group there may be those not fully committed? People who deny this tend to overlook completely wholesale passages that teach the reactions of people to the gospel are more than just two options. some people get truly saved when they come forward and "commit their life" to Christ. Some get saved years after that and others well never get saved at all. Thats how church is people and the apostles knew it.
The FACT of the matter is there are MANY passages that without twisting the scriptures teach very clearly that once someone is truly born again their future is set eternally. People who deny OSAS try desperately to ignore such passages and when they do deal with them they add to the verses clauses and conditions that are nowhere in the text and even change the meaning of the text to suit their theology
That's not the way to rightly divide God's words. The verse that teach OSAS are some of the most straightforward and untwistable passages. The Lord even promises that of those he has been given he will lose NONE
"
39"This is the will of Him who sent Me,
that of all that He has given Me I lose nothing,
but raise it up on the last day.
40"For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day."…"
John 6
Anti OSAS have Jesus lying he will some nothing and in fact claim that many will be lost. Jesus won't be able to keep them from being lost. Nope.....Salvation is not a half way job
"
28And we know that God causes
all things to work together for good to those who love God, to those who are called according to
His purpose.
29For those whom He foreknew, He also predestined
to become conformed to the image of His Son, so that He would be the firstborn among many brethren;
30and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified.
Romans 8
Anti - OSAS have Paul lying and claim anti biblically that all things do not work for good....... but they are wrong. God uses everything EVERYTHING .....ALLL THINGS to bring all who he owns to come through to be glorified in the end
"
37But in all these things we overwhelmingly conquer through Him who loved us.
38For I am convinced that neither death, nor life, nor angels, nor principalities,
nor things present, nor things to come, nor powers,
39nor height, nor depth, nor any other created thing, will be able to separate us from the love of God, which is in Christ Jesus our Lord."
Romans 8
Despite Anti - OSAS claims nothing is in the future of a believer that will render him seperate form the love of God that he has in christ. That rules out the lake of fire for all believers.....sorry
"
4For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith.
5Who is the one who overcomes the world, but he who believes that Jesus is the Son of God?"
1 john 5:4
Despite Anti OSAS claims it is in the nature of all truly born again people to overcome. ANTI OSAS have perhaps millions of believers being overcome by sin and being so defeated they end up in the lake of fire which directly defied what John says - that WHATEVER is born of god overcomes the world.
"No one born of God makes a practice of sinning, for God’s seed abides in him, and he cannot keep on sinning because he has been born of God."
1 John 1:9
Despite scripture clearly and unequivocally stating that a truly born again person cannot go back to continuously living in unrepentant non stop sin for the rest of their life anti OSAS have them not only doing so but doing so straight to hell (can't get more non stop sinning than that)
Notice all these verses are STRONG and unambiguous using terms like NONE, Whatever, nothing . all........indicating clauses without any limit or condition.
All the ANti OSAS have to counter what scripture PLAINLY teaches are passages that warn groups that would have had people at various levels of commitment to Christ not to turn back. How does that outweigh that real believers are said over and over and over in the NT to have real eternal life not only in quality but in duration?
this isn't just about security. this is about salvation being what Jesus said it is - real , complete and eternal
