What is biblical holiness? Can a heart be so hardened that it’s beyond saving? Does the Holy Spirit still give personal promises today? And what does it mean to be truly ‘filled’ with the Spirit?

Tom Wright and Mike Bird tackle four deep listener questions about the nature of holiness, the mystery of a hardened heart, how the Holy Spirit speaks today, and the meaning of being filled with the Spirit in the New Testament. They unpack the richness of biblical language, the difference between human and divine hardening, how to discern personal spiritual promises, and how God’s filling work transforms lives moment by moment.
