Now, I’d like to make something clear. Your faith is not supposed to be invisible. We are called to pray and worship in the community. The problem comes from your heart posture. Why are you posting what you are? Why are you telling people that? What are you getting out of it, and what are the people you’re talking to or posting to getting out of it? You need to be so careful that you are sharing with the right intentions, to show God’s love and mercy, and to encourage others. If sharing about your fasting or prayer life doesn’t encourage or benefit others, then you don’t need to share.
