Going to church doesn’t make you Christian – It’s what you believe and give when you’re there that makes you a Christian. i.e. When you believe in God and give Him every part of you, then you are a Christian.
But even being a Christian isn’t enough, because what God wants each Christian to do is to live our lives in a Christian manner, praying for others and helping them whenever possible. Then others will see God through our words and actions. i.e. Be His church!
