My writing to you is that there is nowhere in Scripture does God encourage secrecy when it comes to sin. In fact Scripture does the opposite, in which it shows God exposing sins, secret sins (Ezekiel 8:6-18). God sent the prophets always as warnings against the Israelites, revealing to the prophets the sins of the Israelites. For example, John the Baptist publicly called out Herod on his sin regarding his marriage to his brother's wife. Through this humiliation we saw the true heart of Herod. He ended up killing John due to pressure.
Also secrecy of sin is dangerous because, sir, our hearts are the greatest deceivers to our souls. The heart is deceitful above all things and beyond cure. Who can understand it? (Jeremiah 17:9).
I take people basically at their word because I cannot read their minds or motives. She stated she repented of this years ago. I started from that point. I'm not talking about hiding sin. I'm talking about leaving forgiven sins behind and not bring them back up.
"Brethren, if anyone among you wanders from the truth, and someone turns him back, let him know that he who turns a sinner from the error of his way will save a soul from death and cover a multitude of sins" (James 5:19-20).
"Hatred stirs up strife, but love covers all sins" (Proverbs 10:12).
"He who covers a transgression seeks love, but he who repeats a matter separates friends" (Proverbs 17:9).
