Amen.
That is how one does it...
From Scripture alone.
Although, if you wish to call the truth, "Calvinism", then that is up to you.
Sure there is...
God's word.
Read it...
If you believe the words on the page, then you should be able to see it at some point.
That is how it happened for me.
I could bridge it for you from Scripture, but then as someone who has believed on Christ for the forgiveness of their sins, you should be able to do it for yourself.
All of God's children have the Holy Spirit, and need not that any man teach them ( 1 John 2:20-27 ).
Study it
deeply, and all things will become apparent, in time.
Provided, time and again, sir.
As for ridicule,
Be careful, utilyan...
You do that all too easily, it seems.
I encourage you to obey the Lord here:
Romans 12.
Colossians 3.
Here are the works of the flesh:
"Now the works of the flesh are manifest, which are [these]; Adultery, fornication, uncleanness, lasciviousness,
20 idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told [you] in time past, that they which do such things shall not inherit the kingdom of God." ( Galatians 5:19-21 ).
Walk in the Spirit, so that you will not fulfill the lusts of the flesh ( Galatians 5:16-17 ).
May God bless you sir.
