It is interesting that in spite of my attempts to test a believer on this forum to see if they are an 'easy believer' or not by asking questions about the view of their own goodness in the light of the Ten Commandments. I have found that all the ones I have asked have avoided giving straight answers to my questions. I find that instructive.
An easy believer is one who has adopted Christianity by preferring to believe in a God of love and not a God of justice as well. They have come into Christianity which really knowing what they have been saved from, and all they have done is to change from one belief system to another, without actually repenting of anything. This is because repentance and forsaking of sin is missed out of the gospel that has been presented to them, and so they didn't know how God thought of them in their unsaved state. Consequently many have become Christians thinking they are doing God a favour by getting on His bandwagon.
So, an easy believer who has no perception of God's justice, is not following the God of the Bible at all, because He is a God of justice as well as of love. He is following a mental image of a comfortable God and a meek and mild Jesus who will love him all the way to the finish without him having to forsake his sinfulness, and as long as he attends church, sings the hymns, listen to the sermons, lives a moral life, and gives generously to the Red Cross, he will be welcomed into heaven.
A gospel that does not include testing an unbeliever's goodness by the Ten Commandments, convincing him that he is not good, and will be found guilty in the judgment and condemned to hell while he remains in an unsaved state, is a false gospel. That is why we have many wishy washy, easy believers who have one foot still back in the world.
