God loves you. God is one God. There is only one true God and creator of all. God is a just God and He is holy. When we were born God wrote His law on our minds (we call these laws morals), yet we have all sinned against God by breaking those laws. Jesus said "You have heard that it was said to the people long ago, 'Do not murder, and anyone who murders will be subject to judgment. 'But I say, if you are even angry with someone, you are subject to judgment! If you call someone an idiot, you are in danger of being brought before the court. And if you curse someone, you are in danger of the fires of hell."
We have all hated or been wrongly angry and unforgiving to others and we should be subject to God's divine judgment. Nonetheless, God loves us very much and He made a way for us to be saved. He came to earth in the form of a man called Jesus. Jesus lived a perfect life (He never hated, lusted, stole, coveted, cheated) and rejected the temptations we as men face. Then Jesus died on the cross for our sins. Jesus died in our place. Jesus who is God, allowed all the wrath due us to fall upon Him.
God did all this because He loves you. If you turn from sin and turn to Jesus, He will forgive you for sin and save you from hell.
