Easy believism. It is the belief (really, the practice) that says that what we Christians need to do is get as many people to walk the aisle, sign the card, pray the prayer as we can. If we can just do this, then we've gotten them into heaven. No worries about whether they actually produce fruit, or whether they become true disciples of Jesus (Matthew 29.18-20). So we heal people lightly. We get them into religion without getting them to Christ. And we have churches (or at least member rolls) full of false converts. We have churches full of people who would scatter like cockroaches should the searchlights of persecution shine upon them. So hear the word of the Lord on this matter:
For you have forgotten the God of your salvation
And have not remembered to rock of your refuge.
Therefore you plant delightful plants
And set them with the vine slips of a strange god.
In the day that you plant it you carefully fence it in,
And in the morning you bring your seed to blossom;
But the harvest will be a heap
In a day of sickliness and incurable pain.
Isaiah 17.10-11 (Emphasis added)
Lesson? Real fruit is better than quick blossoms. Real converts are better than quick professors.
