As an ex-evangelical christian I think I can provide some insight. Christians cherry pick the parts of the Bible they like and are comfortable with, so focus on God's love, and conveniently ignore:
1 Corinth. 6:9-10
Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God.
People are really good at cognitive dissonance!
People go to church for community and comfort. It's often the religion of their childhood so it is a comfort.
My two cents.
