Christian: Under-Construction

Are you a Christian? Do you ever feel like you're displeasing God? Do you ever feel like your walk with God is shaky? Do you ever feel like you're a bad Christian? Do you ever depart from God in prayer, because you feel as if you're unforgivable? Do you feel like you're not doing your part as a Christian? I know. I feel the same way. Just like you, I'm a Christian, a Christian that's under construction.
