Many people judge Christianity based on people they’ve known or read about–and some of them have been pretty mixed up! But not everyone who claims the name of Christian is one, just like wearing a police uniform doesn’t make you a policeman.
While on earth, Jesus Himself was not impressed with many of the religious leaders of His day, who claimed to follow God but who had missed God’s whole heart.
“‘This people honors me with their lips, but their heart is far from me; in vain do they worship me, teaching as doctrines the commandments of men.’” Matthew 15:8-9 (ESV)
Plus, even genuine Christians are just sinners saved by God’s grace–we make mistakes and so often misrepresent our Lord.
Please open a Bible and see what God says for yourself. Judge Him based on Himself, not fallen men.
