To answer point 2) Now this is a loaded question. You cannot be unsaved , unregenerated, un sealed by the Holy Spirit, un seated in the heavenlies , un Sanctified , un justified , un predestined to Glorification ( as that means God is double minded and his promises change ) , un baptised in the Holy Spirit and so much more .
So to help clear the fog . Do you believe a drunkard can be saved by Jesus if so how and why ?
I believe every body can save by Jesus as long as they believe in Him
Let me tell you what I think believe mean
I was immigrant worker in mesa AZ, 30 years ago.
There was a gentelmen ask me how to get los angeles ca.
I told him to take 60 west then 10 west.
Did he believe me?
No body know If he believe me or not, until he take action.
If he di what I say, than I know he believe me.
If he the 60 east than I know he didn't believe me.
We ask Jesus how to inherit eternal live
Luke 10
25 And, behold, a certain lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life?
26 He said unto him, What is written in the law? how readest thou?
27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
28 And he said unto him, Thou hast answered right: this do, and thou shalt live.
Jesus never Lie and He agree that for inherit eternal live require
Love God and love other.
If i have 5 gallon water and i love the poor that ask me a cup of water Will i say No.
I love you brother, but I buy this water I Will not give you for free.
How do you know that I love that poor brother. Just because I say I do love him?
Or by my action.
Remember Jesus say to inherit eternal live, one must Love God and other.
Thats mean If you don't love God and other, you not inherit eternal live
