There is no Scriptural basis for these remarks.
Consider Peter's words about the subject:
For so an
entrance shall be
ministered unto
you abundantly into the
everlasting kingdom of
our Lord and Saviour Jesus Christ. 2 Peter 1:11
There is such a thing as entrance into the kingdom, and a abundant entrance into the kingdom.
Which is what Jesus was talking about in John 10:10 about "having life and having more abundantly".
I clearly was referring to physical birth.
The basis is the fact that we are saved to serve Christ, not just to get something from God and be on our way. We were saved for good works, not for ourselves, but others.
Simple fact is, our focus was on ourselves and what we got before Christ, and afterwards it's about others. It's what we see called "fruit".
However, you say that abundant life is not about others so I will show you some passages.
Proverbs 10:21 (ESV) 21 The lips of the righteous feed many, but fools die for lack of sense.
Proverbs 15:4 (ESV)
4 A wholesome tongue is a tree of life: but perverseness therein is a breach in the spirit.
John 21
15 When they had finished breakfast, Jesus said to Simon Peter, "Simon, son of John, do you love me more than these?" He said to him, "Yes, Lord; you know that I love you." He said to him, "Feed my lambs."
16 He said to him a second time, "Simon, son of John, do you love me?" He said to him, "Yes, Lord; you know that I love you." He said to him, "Tend my sheep."
17 He said to him the third time, "Simon, son of John, do you love me?" Peter was grieved because he said to him the third time, "Do you love me?" and he said to him, "Lord, you know everything; you know that I love you." Jesus said to him, "Feed my sheep.
Mattthew 25
14 "For it will be like a man going on a journey, who called his servants and entrusted to them his property.
15 To one he gave five talents, to another two, to another one, to each according to his ability. Then he went away.
16 He who had received the five talents went at once and traded with them, and he made five talents more.
17 So also he who had the two talents made two talents more.
18 But he who had received the one talent went and dug in the ground and hid his master's money.
19 Now after a long time the master of those servants came and settled accounts with them.
20 And he who had received the five talents came forward, bringing five talents more, saying, 'Master, you delivered to me five talents; here I have made five talents more.'
21 His master said to him, 'Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master.'
22 And he also who had the two talents came forward, saying, 'Master, you delivered to me two talents; here I have made two talents more.'
23 His master said to him, 'Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master.'
24 He also who had received the one talent came forward, saying, 'Master, I knew you to be a hard man, reaping where you did not sow, and gathering where you scattered no seed,
25 so I was afraid, and I went and hid your talent in the ground. Here you have what is yours.'
26 But his master answered him, 'You wicked and slothful servant! You knew that I reap where I have not sown and gather where I scattered no seed?
27 Then you ought to have invested my money with the bankers, and at my coming I should have received what was my own with interest.
28 So take the talent from him and give it to him who has the ten talents.
29 For to everyone who has will more be given, and he will have an abundance. But from the one who has not, even what he has will be taken away.
30 And cast the worthless servant into the outer darkness. In that place there will be weeping and gnashing of teeth.'
