As our sister
@Beckie mentions, some folks see it from day one, no need that any man teach us.
I didn’t grow up in the church, none of my family are Christian. Growing up in the US I obviously heard the gospel and even felt sorrow for my sin and at times attempted to change, read the Bible etc. but it never stuck.
At age 38, I picked up a motel Bible and began reading Matthew, by chapter 18 I truly believed, prostrate I wept in Godly sorrow for what seemed like months. From that day on I became a slave to righteousness, in love with Christ and his word. As I watched my nature change I simply knew this faith, repentance and sanctification was not my own.
Wasn’t until over a year later someone called me a Calvinist, the way they said it seemed derogatory lol. Googled it when I got home, found RC Sproul, Charles Spurgeon, Jonathan Edwards, John MacArthur, Paul Washer etc. It was confirmation for me, I’d only read the Bible and actually attended a synergistic church from day one. In other words, no man taught me. I being born from above by the Spirit of truth, simply read the Bible.
2 Corinthians 7:10
[10] For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death.
