Can people say to God that they are sorry?

People can say to God that they are sorry, 

and He will forgive them. 

The Israelites faced a huge problem because of their sin. God sent snakes to punish them. Anyone who was bitten could look at the snake on the pole and not die. Because of our sin, we face a huge problem: we are separated from God. We deserve to die. Anyone who looks to Jesus on the cross and trusts in Him will be saved and be made right with God.
