People, no matter what denomination, who think being a Christian is ‘easy’, don’t understand that you don’t just say words you don’t really mean and somehow get a free pass.
For those of us that understand the price that had to be paid so we can confidently say “we are saved”, it’s trying to do our best to live a life the way Christ wants us to, but not having to worry when we fail, because we know we can have forgiveness when genuine repentance is there.
For those that don’t realize this, Christianity appears to be cheap grace. To those that have learned a little more about it, they find it is hardly cheap grace.
IMHO, Christianity doesn’t make living the saved life hard, rather our scarred thinking processes, consequential of sin in our life, tempts us to make our life difficult if we fail to remain in fellowship with Him.
