Total utter nonsense! You stopped making sense right after Matt 7:23.
What part of "Not everyone that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." do you not understand? That is cut and dried, Jesus makes no exceptions.
Where does Jesus ever mention any of this?
Let's look at the vss. preceding Matt 7:1-23. I do not see anything even hinting at UR.
Matthew 5:29
(29) And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
If all mankind will be saved righteous and unrighteous alike, why does Jesus NEVER say that and why does He warn about being cast into hell, more than once?
Matthew 5:30
(30) And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
More warnings about being cast into hell and zero mention of universal reconciliation. [UR]
Matthew 6:15
(15) But if ye forgive not men their trespasses, neither will your Father, forgive your trespasses.
People who do not forgive others will not be forgiven not saved!
Matthew 7:13-14
(13) Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
(14) Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
No mention of UR but many, not a few, go into the way of destruction.
But only a few, NOT all, go into the narrow way which leads to life.
Matthew 7:17-19
(17) Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
(18) A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
(19) Every tree that bringeth not forth good fruit is hewn down and cast into the fire.
No mention of UR, every tree, false prophets vs. 15, that does not bring forth good fruit is cut down and cast into the fire NOT saved.
Matthew 8:12
(12) But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.
No mention of UR but "the children of the kingdom shall be cast into outer darkness; there shall be wailing an gnashing of teeth NOT saved.
