The Bible (the word of God) defines what fornication is— it is sex outside of marriage when neither party is married. Adultery is sex outside of marriage when one or both parties are married to another. (Matthew 5:32 illustrates the difference.)
I asked what must I do to be saved, an opportunity for you to present the gospel, to introduce me to Jesus Christ. I thought you’d jump at the chance.
I would have answered with the verses:
Romans 3:23 — admit that you are a sinner
Romans 6:23a — understand the wages of sin is death
Revelation 20:14,15 — the lake of fire is the 2nd death
Revelation 21:8 — all sinners have their part in the lake of fire
Romans 5:8 — While we were yet sinners hrist died for us
Acts 16:30,31— salvation is by faith
(John 3:16, 3:18, 3:36; Ephesians 2:8,9; Romans 4:4,5) — salvation is by faith in his finished work, not in our works
Romans 6:23b — salvation is everlasting life
(Ephesians 1:13,14; John 10:29, John 5:24, john11:25; 1 John 5:10,11) — salvation cannot be lost; if one believes it can be lost, he is still trusting in his own works and has called God a liar
Romans 10:13 — ask God to save you
You characteristically missed placing the first one first: Believe.
If you truly believe (that means believe all that Yeshua said, and ALL of his word) the rest falls in place without using your filthy rags in place of the real thing.
He gave us two commandments, one of which you resist, because love gets in the way of your bitter accusations that make you feel so superior to all those retched sinners.
If you are one of his elect, the Father will introduce you to his son, when the time comes; there is really nothing that I can do to sway you, you are busy being your own savior.
