Mr. Agedman,
1) Can anyone choose to enter the kingdom? Nope. Can most anyone (excluding soil #1) choose to want to enter the kingdom after hearing and understanding to a degree the gospel? Yes. See
Matthew 13:1-23.
2) Can false teaches hinder people from understanding the actual gospel and therefore prevent entry? Yes, see
Matthew 23:13.
3) Can those who have "life" set before them choose life? Yes. See
Deuteronomy 30:19 Does making that choice guarantee the person's faith will be credited as righteousness? Nope.
4) Does everyone have limited spiritual ability such that they can choose life when set before them? Nope, some of lost their ability, like soil #1. See
Matthew 13:1-23.
Can we choose to save ourselves? Nope. Can we choose to reconcile ourselves? Nope. Perhaps you need to stop claiming others believe in free will, when you are really saying they do not believe in total spiritual inability. No need for a smoke screen.
