Blessed is he - a Christian perspective
The man or woman who stands fast in their faith, and who doesn't fall away or let their zeal lessen, is truly blessed. God stands ready for forgive those who backslide and then repent, but is especially pleased with those who hold firm to the faith.
Falling away - a Christian perspective
Paul writes to the Thessalonians and tells them that when the falling away occurs, those who are sinful will be revealed for what they are.
