The Bible is very clear: God does not change His mind. Some people (spurred on by devils and demons) will tell you that God is unpredictable, that He will change His mind if you don’t do x, y and z. But nothing could be further from the truth. The Bible (God’s Word) tell us this:

“God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill?” (Numbers 23:19; NIV)

God doesn't change His mind - Numbers 23:19

Did God change His mind with the Old Covenant?

Sending Jesus to pay for our sins on the cross was never an afterthought or a plan B. Even in the first book of the Bible, the book of Genesis, we can read about God’s plan to send Jesus to redeem mankind:

“And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel. (God speaking to the devil in Genesis 3:15; KJV; emphasis added by me)

In this verse, God is foreshadowing the work of Christ on the cross. Jesus was born of a virgin. Joseph and Mary did not have sexual relations to conceive Jesus. But we learn in biology that man provides the seed, not woman. In this verse in Genesis, God speaks of the woman’s seed, thus foreshadowing the miraculous virgin birth of Jesus.

Has God changed His mind about me?

Nothing you can do could ever undo what Jesus did for you on the cross. Have you accepted His gift? Once you are saved, you can never again lose your salvation. You can never again become unrighteous because Jesus carried all of your sins, your dirt, your filth, your unrighteousness for you when He was beaten and brutally murdered on that cross. That doesn’t mean we will never sin again. We, unfortunately, still sin from time to time. But our actions do not define our relationship with God anymore.

2 Corinthians 5:17 says: “Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!” (NIV) and 2 Corinthians 5:21 says: “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” (NIV)

God does not change His mind. Once you are righteous in Christ, you are forever righteous in Christ. And nothing could ever change that.
