Either way, we must remember too it is the Holy Spirit that does the real persuasion.
I've seen myself and others tied in knots because we aren't sure we said things "just right."
The way God did it in my case was revealing to me about talking to people about salvation. A little background:
Since my parents had a 'MIXED marriage" (as they used to call Protestant/Catholic unions back in the day, and in the '40s for a Catholic to go to a protestant church was a serious SIN, they settled the issue by being neither, but Mom read the Bible to me every night at ed time - taught me how to read in the kjv, in fact. the result was that by the age of 8,9 i was very familiar with the Scriptures and we didattend church sporadically and a preferred the Catholic church, since it was SHORTER, there was a lot to do and see, everybody had a costume and a funny hat on, and they rang a little bell twoard the end to let you know it was almost time to leave (whats a kid know?). since Mom listened to the "Hour of decision" every Friday night on the radio, I found that at the end of the show, Billy would give the invitation, and Beverly Shea would go into "Just as I Am", and I knew that I should do something, but never did - and then after a while the feeling would go away, but I did learn NOT to be around on Friday nights. I didn't know the feeling was the Holy Spirit loading on "Conviction of SIN". Fast forward to '63, and I was essentially at the end of my rope - failed out of School, didn't have a job, was terminally depressed, and at least passively suicidal.
I was in Houston with a married couple the same age as me, and we shared an apartment and one Tuesday I came home from shooting pool, and my roomie Pete was there and his face had the strangest look - almost glowed. So I asked him what was happening, and he told me: "I've been saved".
And I knew that it was true - there it was looking at me Joy, peace 1000 miles deep, confidence - everything I needed and didn't have - so I made fun of him, and went to bed. Pete and his wife went to church the next evening. When they got home, Pete told me that we had to talk.
Now, bearing in mind that I knew the Bible pretty well all the way through, and Pete had never even opened one in his life, which gave me a tremendous intellectual theological advantage over him if I has chosen to argue theology, I could have cut him to ribbons -.
But there was the Conviction of SIN by the Holy Spirit all over me, and even though all Pete knew was what he remembered the fellow who'd led him into salvation had said the night before, Pete presented Jesus, and him crucified as a SIN offering. And I KNEW in the Spirit that ONLY under CONICTION OFSIN was salvation possible, I knew that it had been a LONG time since I'd felt God, and if anything was gonna happen IT HAD TO HAPPEN NOW, and I didn't know if I'd get another chance. Pete's lack of Biblical knowledge wasn't an issue - I HAD TO REPENT NOW and cry out for salvation. and I did, crying out for Him to SAVE ME!!!
And HE did, and everything changed.
It was the Holy Spirit that did the "Heavy lifting" and Conviction of SIN (God's WORD to me) provided the FAITH, and the job got done. I understood afterwards why Paul said the he resolved to know nothing but JESUS, and Him Crucified when evangelizing. So "I don't know enough", or "I'm not good at presenting,", or "what if I saw something wrong" etc. aren't issues at all.
When the Holy Spirit's there, with His Conviction of SIN, you could almost probably read the phone book and they'd get saved.
And WHEN the Person (like myself has become a Christian, THEN it's time to share "theology with 'em like Paul says he does when he's with Christians with some maturity. BEFORE you're saved, God's Kingdom is INVISIBLE. AFTER you're saved, then you have eyes that can see.
