The world is full of evil. If there is a God, why not stop it?

God is just, so he gives people free will and does not force people to choose. He tells people what they can and can't do (people's conscience) and what the result is, but many times people choose to betray God, which is sin.

God is holy, he can't tolerate a little sin, so no one can go to him unless he relies on Jesus Christ, because he is guilty, and the blood of Christ has washed away the sins of all mankind, as long as you believe in him. God's righteousness and holiness are human judgments.

God is kind. When people committed crimes, he sent his son, Jesus Christ, to be born for mankind and be crucified for the sins of all mankind. His kindness tolerates people's sins to the maximum extent (not contradictory to the above). He gave people a chance to repent and longed for people to be saved by believing in Jesus Christ.

My friend Jesus loves you. I hope you can understand Christianity and trust him.
