Beloved,
Know this that all shame is not bad. There is persecution shame. For example the following:
“And they departed from the presence of the council, rejoicing that they were counted worthy to suffer shame for his name.”
Acts 5:41
You should gladly embrace the shame that tries to stop you from publicly identifying with Jesus outside of church such as when you are in a classroom, in the gym, at the mall, grocery store etc.
When the Holy Spirit prompts you to share Jesus do not let the shame of “failure” stop you from doing so. You cannot fail when you share Jesus! If nothing else, you sowed the seed for another believer to Harvest! 1 Corinthians 3:6.
Wear such shame as a badge of honor!
I love you!
