I have heard it presented that way, but that would actually make God beholden to man.
The great bulk of the New Testament, which was written only to those who had received the "free gift", are letters of promise
and warning to those who had been "saved", not to
"shrink back unto destruction" by remaining in their sin.
"Therefore we must give the more earnest heed to the things we have heard, lest we drift away. 2 For if the word spoken through angels proved steadfast, and every transgression and disobedience received a just reward, 3 how shall we escape if we neglect so great a salvation..." - Heb 2:1-3a
"neglecting salvation" is not speaking of people 'not accepting Christ (as is oft mistakenly preached)', but rather of church-goers not walking worthy of the gift they have received.
Paul is very explicit in Romans 6: 1Cor 6:
1Cor 10: Gal 5 and elsewhere, warning that those who had been "saved" yet continued living by their carnal nature
"will not inherit the Kingdom of God." Even
"envy, strife and malice", of which we have seen much from a few of the 'church-goers' in this thread,
"will not inherit the Kingdom of God and of Christ."
Think... would it really be Paradise with such carnal immature attitudes and behavior? No; unless these things are shed - "putting off the old man" (which we must do) - there will not any inheritance in the Kingdom; such as these will not be raised in the First Resurrection, which was Paul's goal, to which he pressed in to attain, knowing that it was not a lock (see Phil 3:7-21). These may be brought in as the inheritance of those who "overcame" ("by loving not their lives to the death"), if Christ (Head & Body) determines them worthy by what they did during their life, at the Second Resurrection. Teaching a series on the Parables of Jeses, I looked at this more closely from Matt 25 - Parables (part 3) SHEEP & GOATS
There is much confusion in the churches at large today, and massive portions of Scripture which must be ignored to accept the modern, popular, ear-tickling theories such as OSAS, eternal forgiveness, a 'state of grace', and other 'doctrines' that teach the "saved" person is okay even if they remain in their sins, and call Jesus "Savior" but never allow Him to be the "Lord" of their life.
Peace & Blessings, Wisdom and Understanding to you, and all who truly strive to walk daily with Jesus.
