Can I bribe God with charity?

If you ever get to visit Kent or Sussex in Southern England, take a couple of hours to visit Romney Marsh and the countryside around. You will find huge, beautiful churches built in places where there would never have been enough people to fill them. Romney Marsh is still sparsely-populated today. These churches were built by those families that had become wealthy through the wool trade. They were built in the hope that God (whoever you presume him to be) would relax the rule about "Rich Men gaining entry to heaven". - Camels and eyes of needles etc. Who knows if the bribe worked?

Why would you want to?

You know what my friend, even if you " sacrifice" yourself for the sake of God, you won't win his heart but do a big sin!

God has everything he is the most powerful, what he wants is our love, our good woks, our true love for him! If you can give that then you will  win his heart! He won't mind if you don't worship him or anything but he would like it if you'd truly live him and be a good person or just a human being!

We have nothing that God wants, so He can't be bribed.

"We are all infected and impure with sin. When we display our righteous
deeds, they are nothing but filthy rags. Like autumn leaves, we wither
and fall, and our sins sweep us away like the wind." Isaiah 64:6

Martin Luther believed, that it is not be "Good Works" but by Faith and the Grace of God that you are saved.

This is the Corner Stone of the majority of the Christian religion . . .

Besides, if the God of the Bible was real, He has already predestined whatever role you play in HIS Perfect Plan via Omniscience . . .  Do what you will or don't, either way the end result He foresaw wouldn't change . . . At all. So glad THAT is no longer a belief I entertain.

No. Bribery of any form is condemned in the Bible. The scriptures show that God strongly disapproves of bribery. (Deuteronomy 10:17; 16:19; 2 Chronicles 19:7)
