During times of need, there is a tendency to isolate. But what we need to do is come back into Christian community. When we fall short of our calling we can experience shame. Peter experiences shame after his denial of Christ. But the others, pull him back into the group. Even in the midst of betrayal and shame Christian fellowship welcomes you back in.
But maybe shame is not the issue for you. Maybe you struggle with doubt like Thomas. Sometimes our doubts are so grand we wonder if we can even approach community at all. Will I be welcomed in? Even in doubt and rejection, there is space for you in the fellowship. Community is a gift from God. We are designed to persevere and strive together. You don't walk alone. In times of shame and doubt, you found a community that welcomes you and through this experience, you, too, will be transformed.
