When people are trying to come to God, or have already come to God, one of the first things Satan wants to do is make people think they’re unforgivable.
Some possible accusations people will be confronted with are blasphemy of the Holy Spirit first, then onto lesser but nevertheless more grievous sins; basically anything to make you doubt you’re forgiven.
If you can get past that, the next thing Satan may do is find ways to make you believe that God hates you, or God does not accept/welcome you, will not allow you into His kingdom, hates your prayers, is grieved by your prayers, etc.
Next, it could include attacks against your finances, property, family, etc.
That was my experience when I first came to Christ.
OP, have no fear. If God be for us, who can be against us? Quite frankly, no one can be against us. So be strong, courageous, and muster the faith to overcome your test. There will likely be more tests after this one, but now is the time to work on being stronger. If you want support, I’m here.
Praying for you.
